It might be legal weight wise.
My f350 4x4 with a diesel, mason dump, and aluminum chip box insert weighed around 9500. Was only good for another 3,000 lbs, or roughly 6 yard of chip. I ditched the mason dump and have an aluminum flatbed and am building an aluminum chip body. The truck is about 1,000-1500 lbs lighter just from that.
That truck shown looks gas, subtract being only 2wd I'd say with that body and a load it was legal. That box sure would fill up fast though!
Def. a cute truck
