I've been considering putting a dump bed on a srw hd pickup. Probably this dump bed. Assume the truck has a gas engine and 4x4. Anyway, about how much grass would I safely be able to load while towing a ~5k lb trailer? I've been doing some research, and it seems like I'd max out the truck pretty quickly. I collect a bunch of grass; right now I'm using a 10x5x5 dump trailer, and there are some days when I fill it up. So that's about 9 yds of grass in a single day. Another option I've been considering is a 1998 chevy 3500hd with a 454 and a 12' dump. The truck has 150k miles but has a new engine and other new parts. My concern is that it'll be difficult to maneuver in town with a trailer.
