im sure all dump bodies are aftermarket, and there are alot of different brands. (Giant, Midwest, Heil, and lots of others just to name a few.)Parts arent that hard to come by though, but ya shouldnt need parts anyway if it works....maybe a seal here or there,and those can be had from about any bearing, seal, or hydraulic place.. theyll run and dump for years with no problems. Pto's and pumps can be seperate or different brands too, but they dont really give much trouble other than a seal,,or even a packing nut that you just tighten up to keep from pouring out oil, a tad bit of leakage is normal with a packing.
