(Edited to say: I am putting some thought into seasonal work at national parks as I get closer to retirement. 6 months at a shot and living in an RV is preferable to a dorm.)
I have lived in many for over six months at a time while working and 4 full time yearly as my main and only occupancy.A 34 ft Terry which was very well made..A 24ft Beaver class c,another well made rv,a 35ft Jayco fifth wheel and my currant Ketstone Springdale.All were with atleast one pet and a kid in Idaho temps.
None were really better than the other as long as you fix thing as they happen and not put it off.I would not hesitate to head out or live in my currant Springdale for as long as I wanted too.
Keep on top of maintenance and you won't have any issues with whatever unit you choose "If" you do a thorough walk through and find one with solid floors/cabinets etc.
