Only for the largest campers with the dry bath do you need a DRW truck to carry the load. For anything smaller, i.e. with a wet bath, the weight can be carried on a SRW truck.
I have used DRW trucks to pull horse trailers and the lack of a turning radius was part of the price. For a camper that required a DRW truck I would sooner get a Class C motorhome and have a fully integrated vehicle and also save a lot of money in total.
For snow or off the pavement use DRW is a decided disadvantage as compared to SRW vehicles. Even the military avoids DRW for all its big trucks and goes to larger tires instead to have a SRW vehicle.
