I'm assuming you're getting a per diem and that it's adjusted according to the cost of living, right? So if you look at that and start doing some research on long-term RV sites you'll get a better idea of what's workable. Many places only allow 14 day max, while others have provisions for workers with RVs and some searching will help there.
If you're in AK and CO during the winter, you're for sure going to need a well insulated 4-seasons trailer. Others can give you brands for that....we're in TN and don't venture out in the winter.
My concern is the dog - forget people, it the animals I worry about, lol. A power outage is a likely thing at one time or another. You didn't mention what hours you work, but you might be able to find the doggie day-care that would be compatible with your work hours. Totally agree that most campgrounds seriously frown on leaving pets unattended, even inside.
My feeling is that you could come out ahead money-wise with your per diem and using that to pay for the trailer and site. It's going to take some homework on your part and doing a search in areas you might be assigned to see what facilities are available and the cost. It certainly would be nicer to come home to your own home/trailer than to a hotel room or whatever you find in the area. Suggestion....you might also ask at the campgrounds/RV parks/etc if they know someone who might come and doggie sit at your trailer while you're at work. Might be a retired person who'd love the extra $ and the company of your dog. Good luck....hope you can work something out.
