All Terrain Campers Puma For Sale - (similar to Four Wheel Grandby)
In good condition with custom build out and lots of extras, making it ready to go on your next adventure. $31,500 USD or $44,000 CDN. Located in Calgary, Alberta, Canada.
We are the second owners. The original owner purchased it new in January of 2012 and used it only a handful of times in the Arizona desert before we acquired it and made it our own. We bought it in 2019 in New Mexico, and since then it has been all over western Canada/USA , from El Paso, Texas to Dawson City, Yukon, never letting us down. This camper has way more storage space than most other builds we’ve seen.
Why are we selling? We’re getting older and have just purchased a 21’ travel trailer.
Includes:
Complete interior rebuild from the aluminum skin in. That means that new rigid insulation, wiring, and plumbing was run. I have lots of pictures so you will know exactly what is behind the walls. Smaller gaps were filled with fiberglass pink, and it was all sealed up with aluminum duct tape so the camper is a lot tighter than most. The factory typically does not run ground wires, which I did so as not to cause hard to find ground faults or loops. AC wiring is not romex, since solid core wires will eventually fail given the vibration of a moving vehicle. I used 12g heavy duty extension cord wire for the longer AC runs. Plumbing is generally not pex, as I prefer screw clamps for easier repairs later on. Braided clear high pressure hose was used throughout.
We like to have a space to move around in and so we purposely did not put in a roll over couch side dinette. Instead we had chair supports that flipped out and flipped down when not in use. These were topped with folding “concert” chairs which we find ridiculously comfy. I have since removed the flip up supports and built a “chuck” box that now lives in the front location because we like it so much. It is easily removed for access to the turnbuckle. The rear location now houses the Joolca brand composting toilet, which is actually a pretty comfy seat too. All that changed in the last year, which is the beauty of having a camper that can be modified… you can always try new stuff to see what works for you!
Interior walls are finished with 1/8” Canadian Maple plywood (similar to Baltic Birch), and simply oiled for ease of maintenance
The floor has 1/2” of rigid foam insulation, ¼” flooring underlay and then luxury vinyl on top of that. It is delightfully cushioned and warm (Warmer than a cold wood/vinyl floor, not like a heated and carpeted floor in your house!)
Ceiling was gutted and redone the same way, with the addition of a layer of Reflectix over the taped insulation. Why? Not for the R value, which is minimal, but to prevent the contrasting pink insulation and silver tape from showing through new roof liner (same material as stock… ATC supplied it). It is all held up with the same 1/8” thick birch plywood as the walls, cut into 1” strips and screwed in place
Permanent Queen Bed – no slide out. Instead there are cabinets and full suspension drawers all along the front wall that the bed rest on, with underbed storage too. We also have a Hypervent underlay to keep condensation under control
Propex 2600 heater – way more reliable than the usual Attwood RV stuff. Heats up the camper in short order
130L Truckfridge (Indel compressor) – mounted as far forward as possible to mitigate the risk of “fridge scramble” on rough roads. We added a child lock for even more security. It has never popped open since. The fridge has an extra 1” of rigid insulation around it to help keep it cool/warm
Induction stove – single burner, portable. We use it both inside and out
Flush mount sink with glass cover, with upgraded stainless steel fold down faucet
12 Volt Shurflo water pump, same as used by ATC/FWC and an Accumulator to smooth out the water pulses
30 gallon fresh water tank with “sight” gauge. This lives at the front of the camper, centered under the batteries and front cabinets to keep the center of gravity low and forward. No gray or black tanks
Awesome LED lighting throughout
All cabinets have lights inside, for much greater ease in finding stuff
Ceiling lights are 48” long to provide a dimmable light over every work surface
Red/Amber and white LED lights in stock factory location over bed
Amber LED porch lights front and rear
Powerful LED flood lights on the rear
Switches for all of this accessible from the outside, just inside the door and mounted on what used to be the rear propane cabinet
2 x 100AH BattleBorn LiFePo4 batteries, external 12V heaters installed (not presently operational… we never really needed this even though we live in a cold climate)
Full Victron charging electronics:
- MPPT solar charge controller
- Victron BMV712 for battery SOC monitoring
- DCDC 30A for charging from altenator
- 4 AWG wire from Anderson power pole to the 100A Blue Sea Breaker in the battery box
- Battery switch to bypass the DCDC and directly connect the camper and truck so the solar panels can charge the truck or, you can use the camper batteries to start your truck
- 3000W AIMS Pure Sine Wave inverter
- AC power outlets (2) in camper are switchable from shore to inverter
- Blue Sea 12V/USB panel with standard and high power USB outputs
- Almost all of the wiring and plumbing is accessible for future upgrades or repairs
T-slot track system installed on roof with:
- 330W glass solar panel
- 2 MaxTrax
- Starlink Antenna mount
- 7 way Cell/Wifi/GPS antenna
- Canoe tie downs
Remote office/work setup with:
- Starlink Gen 2 actuated antenna, mount and cables, converted to run on DC
- PoE 300W injector and 6 port switch
- Peplink Pro router
- All of which enable internet access in most places!
40# lifting struts
“On-Stage” brand Heavy duty Speaker Stand/Lift to raise the roof (we haven’t needed it, but it is mounted to the ceiling in case we ever do)
Fantastic fan with variable speed mod
Arctic Pack
Newer CO/Propane monitor
Custom made two layer high quality queen size foam mattress & bamboo cover
1 year old – 10 year smoke detector
Joolca composting toilet – used sparingly for one season
Hitch mounted step
Fasgun Derringers instead of turnbuckles for secure, never need adjusting attachment to truck
Two “Propane” cabinets. The original one on the rear is now used for storage (water hose, leveling blocks, small propane fire pit, etc) and I installed a new one on the driver’s side close to the front of the camper, thus keeping the weight up front.
4 Removable Jacks with extensions for easier backing and mounting
Water “drain” on the outside has been converted to a metal ball valve and plumbed so that it has fresh water under pressure. We LOVE this feature, as we almost always cook outside. The camper has been cooked in maybe only 2-3 times during super inclement weather.
Water goes through a 3M 0.5 micron filter. It always tastes great!
Zero Declination shower tent mounted on driver’s side – nearly new
Lagun table mount in the “side dinette”
NEMO brand portable shower. We boiled water and added it to this for outside showers. Lovely to have vs sponge baths!
Vinyl windows have been modified to not leak/drip inside when not using the ATC supplied outside rain covers. We found it awkward to use those external covers and the ATC windows can leak due to a possible design flaw. No issues now
No holes or repairs in the vinyl
Marty, of All Terrain Campers gave the camper a once over 2 years ago when we were down in Sacramento, CA and resealed the front (with a “magic bead” as he calls it) so the one time we had water intrusion (driving in an “atmospheric river”) will never recur. He also replaced two of the latches (I have more spares). They also took off all the corner posts and resealed the corners, simply because that’s what they do now and he figured our camper could use all of their latest tricks. He didn’t even charge for this service! Great guys to work with
Camper tie downs replaced with current version which uses large backing plates. I can dig out the matching ones from the truck if your truck has not got them installed yet
Dual 1080p cameras mounted high on camper rear… I had this wired into the truck so I could see with either a 130* or 45* camera for backing or as a replacement for the mirror in the truck. This will need to be rewired for your rig
All construction was with Baltic Birch or Canadian Maple finish grade plywood. Everything is screwed together. No glue or staples. This is for easy access when modifying/repairing the camper
Two newish 10 pound (BBQ size) propane tanks. Certified to….
Also available:
Aluminum NATO jerry can mount and 5 gal 1952 authentic diesel fuel can that will NOT leak
Aluminum holder for 5 pound Propane tank
Stuff I would do as part of annual maintenance
- Roof could use paint, from dragging the canoe’s nose across it. All the screws have been removed, the area cleaned with rubbing alcohol, and the screw re-inserted into a bed of 3M 4200 sealant
- Under cab area – the wood laminate has bubbled in a few places underneath. Marty says it’s no big deal, just sand and repaint
- Cosmetics are not bad, but this is a well-used camper. The worst damage is on the door, where it bashed into one of the flood lights It has been repaired with sheet metal and duct tape, but a new door would go a long way to renewing the appearance of the rig
- At some point before we got the camper in 2019 the propane cabinet floor must have been repaired. Never needed to do anything with it since
- Wood face of the cabinet near the rear is damaged
- Fire extinguisher is old and should be replaced
- The build out has never been “certified”. If that’s necessary in your jurisdiction it could be a show stopper. I tried to design and build everything to meet or exceed the relevant codes, but this is definitely a “home built” unit
- Previous owner also bent the roof on the driver’s side, forward most side clip. I have repaired this using a method Marty at ATC recommended. It is still visible and causes the liner to sag slightly but we have a board we insert on the inside to straighten it out while popped up
- The vinyl windows have never quite lined up perfectly since we got the camper, so one needs to pay attention to lining them up right when closing up the windows in preparation for dropping the roof
- I never got around to installing a proper ground buss bar, so most grounds end up on the shunt
- I would not use luxury vinyl again, as it dents and cuts easily. Ours has a few nicks, is still functional, but not pristine.
