For that price I'd take it. I don't know about filling the whole deck in with boards. It might be nice to work on the vehicle with it on a trailer. I don't know though, it may be a pain in the ass working under a trailer and not worth it since you have all the crossmembers in the way anyways.
Definitely put brakes on it if it doesn't have it. Any slight bumper bender you get in could end up in one hell of a lawsuit.
