I bought a few RVs during the 25+ years I lived in Alaska. Three or four of them, I bought off the "lemon" lot of used vehicles out on Elmendorf Air Force Base. All ended up financed through the military credit union so I dealt with the credit union for the most part. Some of the owners had already rotated out of state at the time of sale. But the credit union held the title and power of attorney on the rigs to sell them.
Usually got a price that I considered fair. A couple I bought in Fairbanks from private sellers and one new one from a dealer there. Like anywhere, it is a matter being patient and keep looking. Owners in Alaska are no different than anywhere else in that they want, and want is the key word, top price for their rig. Especially if they paid sticker price for it when they bought it originally. Also bought a couple of motorcycles from the lemon lot at JBER. (new name for the joint bases)
Looking for a specific model and brand may turn out to be difficult to find in a small market such as Alaska. I would keep my options open for any with a likeable floor plan and a size that would fit my truck. Personally I don't believe there is much difference between the brands, my last two truck campers have been Lances, but the previous three were other brands. Had just as much fun with them as I have with the Lance models. Maintenance not any real difference in the overall scheme of things.
Check with some of the RV rental places that have TCs and see if they have anything coming out of their rental fleet. Most of the Alaska rental companies seem to mainly have Class C rigs but I do see a few TC rentals up there from time to time. We try to get back up every couple of years to visit friends.
