I am planning on downsizing my class A to a B+ rv under 25 foot, was also looking at new trucks and a camper as a 2nd option, so with the price of a new F-250 to F-350 and a new camper with a slideout...
While I agree the prices are steep, I would never do a one-piece. I like being able to separate the two, plus, I need a truck anyway. Plus I like to go where you can't really get a bigger one-piece or trailer in.
