9 Largest Truck Campers That Blow Our Minds

These days, the largest truck campers can available come with up to 3 slide-outs that can honestly make you forget you’re in the bed of a pickup truck. With all elements considered, the Rugged Mountain Denali 3S is the largest truck camper in most categories. However, the previously manufactured Eagle Cap 1200 and Eagle Cap 1165 are also pretty massive. 

Join us as we examine the largest truck campers. We bet you’ll be amazed!

The 9 Largest Truck Campers

We personally like comparing camper models in tables with their numbers. We’ll dive more into each model’s features below, but this comparison table shows how they stack up on specs.

Note that each rig comes with a different set of standard features, different builds, and different layouts. By adding options, your weight can increase even more, and you need to account for that in selecting a compatible truck to carry it.

Let’s take a closer look at each of these models.

Can you believe this is a truck camper interior? It’s huge!

Rugged Mountain Denali 3s

Rugged Mountain RV produces made-to-order four-season truck campers. Since each truck camper is custom-made, the company only produces about 20 units yearly.

While most truck campers use an aluminum frame, Rugged Mountain RVs use a stick-built wood frame. The company produces five truck camper models, Denali 1S, Granite 11RL, Granite 9RL, 12SE, and Denali 3S. The Denali 3S Flatbed Truck Camper is the largest.

  • 3 slide-outs: Two slides on opposite sides, and one is in the rear. 
  • It is 20’6″ long
  • Interior height of 6’8″
  • Dry weight of over 5,500 pounds
  • Tanks: Fresh tank capacity of 80 gallons, a gray tank capacity of 77 gallons, and a black tank capacity of 35 gallons.

The extra space in this truck camper allows it to have some impressive features. It has stainless steel residential appliances, a high-efficiency Houghton 12v air conditioner, and a heated basement. Additionally, it has double pane windows for four-season adventures, a roof skylight in the bedroom, and two Fantastic fans in the kitchen and bathroom.

The 3 Largest HOST Truck Campers

HOST Campers was started in 2000 by the sons of Jim Hogue and Frank Storch, the founders of the Beaver line of RVs. The sons, Dave Hogue and Mark Storch, grew up around RVs, as their fathers started the Beaver line with truck campers in 1966 before shifting more toward Class C and eventually Class A motorhomes. 

HOST Campers has 6 models of truck campers (2024) that are made in Bend, Oregon, all of which have at least 2 slides and 3 of which have 3 slide-outs: the Mammoth, the Yukon, and the Everest.

  • These campers have lots of options and features that can be added – including king-sized beds!
  • They are above-bed designs, so their floors are above the top edge of the truck bed to provide that open-space feeling.

1. Mammoth Truck Camper

The HOST Mammoth differs from the other 3-slide models in that it has its entry door on the back wall of the RV. As a result, the side slide is bigger and the rear slide is smaller.

The shower is located in the middle of the camper and has a pass-through design bathroom on the driver’s side slide that can enter into the bedroom. This model features a larger dinette and a couch/theatre seating option in the rear unless you opt to turn this into a laundry center or wardrobe.

  • Floor length is 11’ 6’’
  • Dry weight comes in at 3955 lbs
  • Tank capacities are 65 fresh, 51 grey, and 32 black
  • Propane capacity is 15 gallons

2. Yukon Truck Camper

The HOST Yukon has the passenger side entry door, making the rear slide bigger than the Mammoth’s. This rear slide consequently holds the main seating area, either in the form of a dinette, couch, or theatre seating. The smaller driver’s side slide has the pass-through bathroom that now shares the space with the couch/wardrobe/laundry center options.

The HOST Yukon truck camper standard specs are the same as the Mammoth.

  • Floor length is 11’ 6’’
  • Dry weight comes in at 3955 lbs
  • Tank capacities are 65 fresh, 51 grey, and 32 black
  • Propane capacity is 15 gallons

Additionally, be sure to check out the floor-to-ceiling window on the driver’s side in the picture below!


3. Everest Truck Camper

The HOST Everest Truck Camper is very similar to the Yukon with its passenger side entry door but swaps the galley with the dinette so the kitchen is now on the driver’s side. However, the fridge remains on the other side of the camper. 

The HOST Everest truck camper is a little lighter than the other three-sliders with a dry weight of 3890 lbs. We’re not quite sure where the 65 lbs was lost in comparison to the other models by just looking at the floorplan, because it is the same floor length as the Mammoth at 11’6’’. Tank sizes are again the same with 65 fresh, 51 grey, and 32 black. 


Lance 1172 Truck Camper

Lance Campers has been making truck campers since 1965. This California-based company also makes travel trailers, but their legacy is rooted firmly in their truck campers, of which they have 9 current models. The 1172 is the biggest of these models, and Lance’s flagship truck camper.

The Lance 1172 truck camper has 11’ 11’’ of floor length, meaning it overhangs the end of a long-bed truck. It has two slide-outs, one on the driver’s side of the camper that contains the dinette and one out the back of the vehicle that has a sofa that converts into another bed. It has a dry bath, a queen bed, and 6 cu. Ft. refrigerator. It has 42 gallons fresh water capacity and 35 gallons of each grey and blank tank capacity, so it enables longer periods between fills and dumps.

The 2024 Lance 1172 truck camper weighs in at 4318 lbs dry with standard equipment and 4772 lbs once you fill that 42 gallon fresh water tank and propane.

The 3 Largest Eagle Cap Truck Campers

Eagle Cap was founded in 1969 by Erdman Epp and was acquired by Washington-based Adventurer Manufacturing in 2011. In 2022, they put an “indefinite pause” on the Eagle Cap brand name. These truck campers were just too huge and unique to not be mentioned in this list, despite their production stoppage.

The company continues warranty and servicing for all actively registered Eagle Cap units. While they are no longer produced, used Eagle Cap truck campers are highly coveted, due to their reliability and durability.

1. Eagle Cap 1200 Truck Camper

This is one of the largest truck campers Eagle Cap makes and has 3 slides – one on both sides and one on the back. The Eagle Cap 1200 truck camper has the “above the bed” floor design, meaning that the floor doesn’t sit down in the bed of the truck but rather above.

This enables a flat open floor space – over 100 sq feet of it when all the slides are out! The overall heights of these truck campers are taller because of the higher floor, and this can mean that the center of gravity is higher. (Check out what a higher center of gravity means for driving a truck camper.)

It has two entrances to the bed area with the dry bath located in the center of the floorplan. With roomy counter space in the galley and two couches off each other the other slides, this camper can host – and sleep – half a dozen people. 

  • Dry weight is 4870 lbs
  • Generous tank capacities of 66 gallons fresh, and 34 gallons each of black and grey
  • Wet weight well exceeds 5000 lbs

2. Eagle Cap 1165 Truck Camper

The Eagle Cap 1165 is also a triple-slide unit above the rail, but the passenger side slide is only for the fridge and stove. A cool island galley comes out from a shared wall with the bathroom. The huge living area fills the 102” width with a dinette and a large couch. 

The 1165 has a floor length of 11’11” and weighs in at 4917 lbs – about 50 pounds heavier than the 1200 model. It has 66 gallons of fresh water capacity and 41 gallons in its grey and black tanks over the 1200 camper. Whoa!


3. Eagle Cap 1160 Truck Camper

While not as big as the 1200 and 1165 models, the Eagle Cap 1160 only has 2 slides and weighs in at 4659 lbs – which is still larger than the largest Lance truck camper! It has tank capacities of 66 gallons fresh, 44 grey, and 44 black. It still has the wide 102” Eagle Cap Exclusive width, 11’11” floor length, and the above-rail floor design. 


Honorable Mentions: 

1. Arctic Fox 1150 Truck Camper

The largest truck camper that Northwood Manufacturing makes is the Arctic Fox 1150 Truck Camper. Northwood Manufacturing also makes Wolf Creek Truck Campers, but all are smaller.

The Arctic Fox 1150 isn’t as big as the other truck campers listed here as it only has one slide. However, it does weigh in over 3000 lbs (3358 lbs dry, to be precise) and has a floor length of 11’4’’, so it’s worth consideration as another large truck camper brand option. The single slide is located on the passenger side of the vehicle and holds the dinette and fridge space.

  • With 59 gallons of fresh water, it exceeds the water carrying capacity of the Lance 1172.
  • For its other tanks, it has 35 grey and 43 black capacity
  • Carries 60 lbs of propane
  • The Arctic Fox comes with an option of having either a wet or dry bath area and has a rear entry door.

What Are the Largest Pop-Up Truck Campers?

Pop-up truck campers are truck campers that have collapsible roofs to save height when traveling. These campers are generally smaller, don’t have slides, and weigh much less than hard-sided truck campers.

  1. Alaskan truck campers are notable for their hard-side pop-up design. Due to the hard-sided materials and more robust lifting mechanisms that go with it, the largest pop-up camper is the 10′ Alaskan Cab-Over Truck Camper. It has a dry weight of 1985 lbs and a wet weight of 2250 lbs.
  2. 2024 Northstar 850SC with a dry weight of 1785 lbs and an overall length of 15 feet.
  3. Hallmark flatbed truck camper can weigh up to 2800 lbs, depending on options.

How Much Does A Large Slide-In Camper Cost?

A very large new truck camper like one of these typically costs between $50,000 – $85,000, and possibly more depending on the options and package you choose to add on. If you don’t have a capable truck right now, remember to factor that big diesel dually into your RV budget, as well!

Large Truck Camper Considerations

The largest truck campers available today are big and weigh in at well over 3000 pounds. Because of this, they require a one-ton or larger truck, usually a diesel and a dually, to carry that RV weight safely and legally. When considering getting one of these large truck campers, you’ll want to ensure your tow vehicle is compatible. 

Besides needing a substantial truck to carry these truck campers, it is also wise to look into possible suspension upgrades to ensure a stable ride. More robust sway bars and airbags are smart in order to have more control over your vehicle’s handling.

Benefits of a Large Truck Camper

The major benefits of these truck campers are their comfort and where you can take them, especially on longer trips. While their size limits extreme off-roading, they still get you into smaller campsites and further off the road than most other types of standard RVs, thanks to the 4×4 capability you can get in your truck.

What is common among these large truck campers is that they all have slides or pop-outs. While a big reason for the massive weight, these are key to expanding the interior living space drastically. This allows for roomy features like dry baths, extra couches, and sleeping for up to 6 people.

Is The Biggest Truck Camper the Best?

Is bigger always better? When it comes to truck campers, or any RV for that matter, it all depends on what you want to do with it. So, the best truck camper is going to enable your adventure and provide you with the level of comfort you need. 

For some, getting way out in the boonies with an intense off-road truck camper may be the best option – but that isn’t going to be true for the person who wants a dry bath, lots of counter space, and a big comfy couch to relax on at the end of the day of exploring.

For us, we loved having the extra space that the larger Lance 1172 truck camper provided for our 6-month Alaska expedition to the Arctic Ocean. We also had 2 dogs with us, and they needed the extra floor space to be comfortable, too. We were able to go everywhere we wanted with this setup, we just needed to be mindful of our height and weight when off-road.

No Matter Which One You Pick…

The best thing about truck campers though? You still drop the camper if needed! So if you want to go down that windy two-track, you can unload the truck camper and go in just your truck. So, whatever size and capabilities you prioritize in your truck camper, you still have way more versatility and flexibility than practically any other RV out there. 

Do you have one of these large truck campers? We’d love to hear your thoughts! Drop us a note in the comments below what you think of these truck camper beasts.

Great article. While you did mention it, I don't think there is enough emphasis placed on the fact that the manufacturers weight spec rarely applies in the real world, since it doesn't include options that many (or most) campers will have. These can be heavy items like a generator, the Arctic Fox "Fox Landing" and even air conditioning (which many people in the south may forget is an option). I would imagine that the most commonly fitted campers will scale around 600 to 800 pounds more than their data plate figure, dry and empty.

Keep up the good work, I enjoy all of the subjects that you cover.

We have been traveling in our 2020 Ram 3500 dual and Eagle Cap 1165 since March of 2020 throughout the Southwest,Sierras,Rockies, Baja and down through central Mexico down to the Yucatan and home without an incident. After traveling over 25,000 miles we had the unfortunate circumstance of breaking our truck frame last November when we traveled back down to Baja. Yes we are the ones who were all over the internet last month with the broken truck frame. As it worked out we got back home safely and the insurance paid for a new frame. We plan on selling our one ton truck and getting a Ram 5500. One of the reasons we made the decision to buy the Ram 3500 to haul the camper was following your Go North Alaska trip in your one ton truck. Please advise your followers that a one ton truck does not have the payload capacity to haul these big campers.


Monday 5th of February 2024

@Mike Pavel, I think I saw your picture (blue pu?) and surmised you didn't have a long bed on your 3500. I have an '05 dodge 3500 diesel (5.9 Cummings) dually w/ long bed, rear airbags (@ 60 psi) and hauled an 1150 Artic Fox (4000 lbs.) all over the USA for 10 yrs w/out a problem. I added a Torklift (?) extension (5 or 6 ft. I think) beneath the rear overhang of the camper in order to tow a car trailer with track-vette for 5 yrs. between Florida and Michigan and tracks in-between with no problem. I would get 15 mpg at 65 mph if going with the wind, and 11 mph going against the wind (it was tough going East to West across the Great Plains). Once going from the East gate of Yellowstone to the S. gate, I got 28.9 mpg towing a motorcycle trailer--the truck coasted nicely down the mountain sides (6-speed manual). Wish I had bought another truckcamper instead of a toy hauler two years ago--now I have to sleep in the bed of the truck or in the car trailer w/o amenities when at the track. I put this info on here to inform others of what worked for me and why. Trust you are having a great time w/ a new rig.

Hey Mike thanks for your comment. So sorry to hear about your trouble but yes we saw that pic all over the internet. :( Glad to hear you're going with a heavier truck. Your Eagle Cap is significantly heavier than 1172 we had but I agree that doing it again we would go with a bigger truck as we were right at the limits. Our current 5500 is so much stronger in the frame that it makes the one tons look small. Although we're not as heavy with our current camper the off-roading we do would probably snap a one-ton frame.

Great article! I have been searching for truck bed campers with side entry and this gave me more options than just Lance, thank you. We will be towing a trailer and my biggest concern is how large a trailer we can tow with one of these large truck bed campers. Is there one that is built to tow better than the others? Putting a long extension out the back from the truck’s receiver scares me. I wish one of these campers had some sort of option that moves the receiver to the end of the camper but is reinforced enough or ties back into the truck receiver somehow. Or offer hard points on the back of the camper that can vertically support the long extension for the trailer tongue weight. Any info on this? Thanks! Jason

Hi Jason, yes that is a serious limitation with these rigs. We tried to run a stinger hitch while using the Lance 1172 and opted to ditch it because of the low departure angle it created and the weight concerns. To haul any serious weight behind a rig like this you're going to have to look at a bigger truck - 4500-5500 class range. Honestly, it's why we went to the Ram 5500 with our new build:

Your Go North series was very valuable to us when we considered the purchase of a truck camper. Ultimately we selected the Arctic Fox 1150 and matched it with a Ford F350 dually.

I’m curious about the wet weight of your Lance 1172 and F350. Our setup is always pushing or exceeding the 14,000 lb GVWR of the our truck. I assume you had the same issue considering all the gear you hauled up to Alaska.

Mortons on the Move

Friday 28th of May 2021

The truck had a GVWR of 14000 lbs, and the truck camper came very close to that number. Because of this, we modified the truck to better handle the weight. You can read about the modifications in this article:

We had a Lance 1171 camper on a one ton dual that we camped in for several years. It had one slide on the driver’s side. It took some getting used to as far as comfortable living goes after our 36’ Winnebago Journey, but we did enjoy camping in a much smaller footprint. The downside was not having a good comfortable lounging place, and the difficulty of loading and unloading it from the truck which is not as easy as it sounds. We did take it to Alaska and it, on our 4x4 truck, gave us a lot of confidence on many dirt roads for true backcountry camping. Things to check out before you buy: Inconvenient propane filling if your new rig requires lifting the 20lb cylinders down from their storage space to fill. Remember you also have to get them back up when they’re full. Comfortable Lounge space and access to the tv Wasted weight such as the very heavy mirrored doors on the bedroom closet ( ours got replaced immediately with curtains). Weight is a definite factor once you start adding clothing, food, water, propane, etc. Top heavy weight distribution makes cornering or uneven slanted roadways an adventure. The truck is EVERYTHING. Make sure your truck choice is up to the task and don’t listen to the salesman when it comes to truck choice. Camper salesmen will always tell you what you want to hear in this area. Your PAYLOAD is the determining factor and you risk massive damage if your truck isn’t up to it. Loading and unloading is really a two person job. If you and your spouse can’t work together on this, don’t even think about it. Don’t plan on unloading at the drop of a hat because it’s not as easy as some videos would have you think. Very level, solid surface is key.

Hey Laura - Thanks for all of these great tips and for sharing your experience with the Lance 1171. You are right, the truck itself is a very important factor!!
