Well asking all things of anything is usually not realistic, however if by fast you mean as fast as the 14 or faster, and by camping you mean really rustic, (use a 5 gal bucket for a potty, tarp over the boom, sleep on the tramp) then you really only need 2 coolers tied to the boat, one for beer and the other for beer or dry clothes and small blanket). The Hobie 21, with gizmo on the front crossbeam is about as close to a fast cat with storage that I have seen. once you ask for real storage on a cat it starts to make the hulls wider and thus slower. Was on a stiletto 30 great boat, moderate storage, could sleep in if it was raining, but not a screamer. If a motor boat is a consideration, get towing insurance. I like to keep the performance of a cat separate from living arrangements, drive somewhere, set up camp and sail from there or to it.
