Thoughts/Suggestions/help on this new truck I bought

The prices ive been seeing are out of this world and totally unrealistic.

What is the easiest and most profitable unit I can put on this thing? a dump bed? And what are the specs needed for anything to fit?

I feel like those things suck and people would rather have a flatbed lol… If im not going to keep the truck I want to either A - sell it as is and let someone put whatever they want on it or B - purchase a cheap, but profitable body for it like a dump bed.
