Right truck and camper setup for a northern Alaskan winter

Hello everyone, this is my first post on this forum, so before I start talking about my requirements, I will talk a bit about myself. I have been actively chasing the Aurora Borealis since 2016 and although I have chased it outside the United States a few times, 99 percent of it has been from Alaska, more precisely, northern Alaska. A lot of my travel takes me north of Fairbanks into the Dalton Highway and I have photographed the Aurora from almost every nook and corner of the Dalton till Prudhoe Bay. I started by renting cars from Fairbanks and then because of covid last year, I got an opportunity to spend a winter near Fairbanks and remotely work from there and go at it the entire winter. I also wanted to have my own car, which is a 2017 Toyota Land Cruiser, and wanted to be in Alaska starting fall, so I even towed my Lance 1685 travel trailer and camped all over the Dalton throughout the month of September. Was it the most pleasant experience towing a Lance 1685 with a Land Cruiser? I will definitely say no but it did the job just fine. I was hauling 25 gallons of gas and 40 lb propane on the rack of my car as well, so climbing up steep hills, expecially the Atigun Pass was not fun, but again, it did the job. That was back in mid-September when a sudden cold front moved in while I was camping in the north slope and pretty much transformed the entire area from a fall landscape to a winter wonderland. It was the first time I realized a camper would have been so much better when descending the Atigun Pass on my way back, I was going all over, the trailer was pretty much pushing the cruiser down in whatever direction it wanted to, I had to be very careful with the brake controller and kept adjusting it throughout the descent to make sure the wheels of the trailer do not lock. Probably the most nerve-wracking experience of my life but I did learn a lot from that incident. I have pretty much parked the trailer in front of my Airbnb for the winter and have been exploring in the cruiser and its pretty much made for that, but I do end up needing to sleep in the car for multiple nights, not that its impossible but I am getting old and I personally feel I am ready to start bringing a camper along with me during the winter months as well. I have driven so much on the Dalton in the harshest weather that I even understand small local weather and wind patterns there, so if I ever have to do it, now is the time, and I see so many truckers pulling such heavy loads, so I will take it as a learning curve. Another big reason is I travel with 2 cats, they traveled with me in the trailer and I having a camper will solve the problem of needing to leave them behind as well. I stay in a pretty remote Airbnb east of Fairbanks and power cuts are not that uncommon there which pretty much shuts the heat off, so I have gone above and beyond to get notified of something like that happening but nothing beats having them with me all the time. So that's why I am here, I am planning this trip starting this fall from Seattle WA and I will need to get a truck as well as a camper that will be suited for this job. I might keep the cruiser, I might even sell it, I have not decided that, it's an amazing car. I also have plans to visit Dempster Highway in Canada and drive up to Tuk in winter as well, could not do it this year due to Covid restrictions in Northwest Territories. I might eventually end up buying or building my own place in Alaska, so having a capable truck will definitely come in handy. That's where my lifestyle has been heading over the last few years so I do see it as a good investment. I need some help in deciding both the truck and the camper. For the camper, I have my eyes on the Northern Lite campers, not a big fan of Lance, it did well but I had to put bandages all over the interior to make sure stuff stayed in place, otherwise, everything would have come off from everywhere, even at very slow speeds if the road gets bad. But I am definitely open to all suggestions. I consistently stay and shoot the lights at extremely cold temperatures. This year, I have even stayed out in my car with temps hovering around -60F. I don't care about restrooms, good to have it in fall but I don't expect it to work in winter. All I care about is some heat inside, a bed to sleep and a small kitchen to make some food, and most importantly, the ease of having to maintain and drive it in such conditions. The last point also holds for the truck as well. I might park the camper from time to time to explore the area just in my truck so that might be a consideration between DRW and SRW but I have almost zero knowledge about it. Sorry for being ignorant about these things, I am always good at planning and executing things but with these trucks and campers, I always get very overwhelmed and lose my way completely. I am happy to answer any questions, go and look at resources, any help will be appreciated. Given demand and supply, I think I have to act pretty fast if I have to make it happen this Fall. I am sharing a link to a bunch of pics that I could find where the road is visible, that will give you guys some idea as to the type of roads I am talking about. I am not interested in extreme offroading, my offroading needs are mostly governed by the destination I want to reach or what I want to do. I will prefer reliability over capability in a terrain and place like this, thats the very reason I sold my Land Rover for the Land Cruiser before I made the trip last fall and that was the best decision I took.
