I live full time in a toy hauler. I work remotely (full time), and stay mostly on BLM and NFS public land. My camper is a Northwood Mfg Desert Fox 24AS.
I looked at the ATC just now. Two issue for me come to mind; insulation isn't as good (i also didnt notice double pane windows) as northwood or orv, and the ATC is low to the ground. Both ORV and northwood are 'lifted' with pretty good ground clearance, and also keep in mind their frames are designed for offroad use.
The orv 24trx is a trailer i'd like to switch too. mainly b/c the tongue weight on my 24as is 2000 - 2200lbs; and even though my truck is a 3500 srw standard bed, 2000lbs is just too much. (honestly i wish i had gotten the long bed, i feel like the long bed may handle the higher tongue weight) the 24trx has a nicer interior and almost 1/2 the tongue weight, though 24gals less water. However, i do carry a 35 gal water tank in the bed of my truck. i love having this extra water - i can leave the camper and run somewhere in the truck to fill it up without having to move the whole camper - it allows me to shower more frequently.
If i were you, i would make the trek out west - sold as far east as denver - and get a northwood or orv. i've winter camped numerous times in mine, for weeks at a time at -0 temps - only issue i've had is with my refrigerator on LP - (personally, i'd like to have a DC only refridgerator). Keeping the thermostat on 60, a 30lb bottle will last about 4 days, so not too shabby.
