Wow, you guys are great. I run 17.5 inch wheels on this thing so clearance may not be a problem. These big hubs run ball bearings and I'm aware that rollers are a pretty important upgrade as well. Some of what y'all decribed makes sense to me and some of it would require a visual to completely get my mind wrapped around...

MNSmith, do you have a salvage yard???? I like your idea alot...
