For the trails I think I'll just air down a bit. Don't think it will be a problem. On the road, traction in the rear could be a serious issue for me. I have an aluminum flatbed that weighs like 3 pounds. Even on flat ground on snow in 2wd my rear (w/detroit) always tries to catch up with the front 
I'm really worried about my rear slipping out at higher speeds and puttin me in a ditch. (I know it sounds pessimistic) I think I might need to pickup a set for front and rear. Prismo told me he uses ones that have little pieces of metal (welded on the chain) for better traction? Anyone know where I can order a reasonably priced set. I dont think many places in MO would sell them
if i was you i would drop that tool box into the bed, so that it sits on the frame, then ad some weight to the rear, a good heavy bumper and some trail armor would be nice, and will help you flex better
