Probably will tow a cargo trailer with bike or quad or something. You running a diesel, or gas?
The problem with a shortbox camper is that you are limited to a 2500 pickup, the 3500's are all long box except for a Dodge megacab dually.
Arctic Fox was bought out by Mallard a couple years ago. The quality has went down hill under Mallard management. We have a very large RV dealer in this area and they sell Lance campers, for a long time last year they had a 1 year old Arctic Fox camper right out front that had one side completely de-laminated. The Arctic Fox dealer in town would not repair it or even look to the manufacturer for a fix. Just said out of Warranty. This was a very powerful sales tool for the Lance dealer.
MORSNO is right the AF weigh a lot more than any other camper.
25 years ago we hunted out of a PU camper in Montana in below zero weather. One of the problems we had was condensation at night while we slept and cooked. PU campers due to weight restrictions are not very cold weather proof so unless wintering in warm climes this needs to be contemplated.
We managed to keep warm via the propane heater but another problem was the battery would run down overnight and not supply enough voltage to operate the sail switch in the furnace to turn on the burner resulting in it blowing cold air for several hours in the early morning . Yet another consideration.
Camping in cold weather is not all its cracked up to be!
That works! Just make sure you have good tires on your truck, an 865 is still in the 4,000lb arena. I think it's Toyo that makes a LT tire rated at just over 4,000 lbs, most are around 3,500lb and a few are closer to 3,000lb, the light load tires will overheat and blow out with a 4,000lb camper.
