The inside of that body looks to be in good shape as long as the conveyor is not seized up, couple gallons of waste oil sprayed on the chain would work wonders.
Check the side dump hinges also, once they seize up you have a bad job on your hands, a few shots of grease works wonders.
The rubber wiper is partially missing from the headboard too, not a big deal but you'll lose product .
It does drop salt or sand ahead of the rear axle which is good but the bad thing about them is it drops salt over the frame from leakage of the return tray underneath, totally covering the frame in salt.
Depending on how the side dump/reloading cylinders are configured it can be hard on the moveable section as well as the main frame rails of the body. If they're at a really low angle (which some are) it pushes the moveable section and the frame rail apart until it gets high enough to move it up easily. If you get a ham handed operator that tries to reload the conveyor before the product is low it's not good.
Still think it's worth $$$ to trade for a conventional
