You want to haul and tow at the same time.
Does your truck have single rear wheels (SRW) or dual rear wheels (DRW)? DRW provide more stability and allow you to haul and tow more weight. DRW struggle on narrow dirt roads and in sandy situations offroad.
IMO know what your trucks capabilities are before you select a camper. The rear tires will dictate the amount of weight you can haul and tow safely.
8' campers are lighter than the longer campers. 8' campers make it much easier to tow heavy trailers. Only a small portion of 8' campers have all the amenities you are looking for (bathroom). If you have a SRW truck you will want to find a 8' camper.
Longer campers really add weight and you need to add special towing hitches (Reese Tow Beast or TorkLift Superhitch) Much of the camper's weight and all the tongue weight (15% of the trailer weight) sit on the rear axle. There are quite a few campers made that are over 4000# and even a DRW struggles with the weight without pulling a trailer.
Truck campers (TCs) are very expensive (per square foot) compared to other types of RVs. TCs are more plentiful out west and probably quite scarce in your part of the country. Used TCs can be found with patience and searching, although it is a much easier task out west.
