I realize it won't go the places the PU with camper can but just where can it go?
You just might be surprised.I really can't think of any place I have been with any of my pickup campers (all on 4X4's) I couldn't go with my currant Class C or even the 24' I had but I don't "hard Core 4X4" with a heavy camper on because things get broke with all the twisting and bending involved.
Those that have not owned pickup campers don'r realize how top heavy they are and the jacks stick out and hit things..Without the jacks mounted is much better,in my opinion..I loaded with suicide jacks on a couple.
The larger Class C you go will limit your abilities even going in and out of little camps because they will drag the rear.Been there done that on Class C's/travel trailers and pickup campers.
Think short and ground clearance and you will probably go where you went before.I chose the class C I have because it will get into places I couldn't get into with my 26ft trailer and even the smaller trailers because of total length...
