Well, being a grad student with a thesis topic involving non-destructive testing of concrete, I get to play around with the heavy stuff a lot. We're about to enter into a test phase and have to pour 2 small (4'x4') slabs, but the budget is tight, so no ready mix truck for me. I get to go to Home Depot and buy 20 80lb bags of the stuff (1600lbs), in addition to a few sheets of plywood and some 2x4s. So, all told, with the cap and the rest of the junk I have in the back, I'll probably be pushin 2000lbs in the bin (rated for 2475). Should prove to be interesting with the poor ol 305 and 3.42 rear, especially climbing up the mountain. Anybody want to give odds on whether she'll hold up or blow up? Good thing I have the heavy duty springs/brakes option on top of the regular C20. Maybe I should wimp out and make 2 trips, any opinions? You know if something breaks, I'll be crying to you guys for help
