The k5 should be light(er) because it is missing some parts etc, but it's a 4 hour drive. I have a 1990 GMC F/S Jimmy I will be towing a 1979 K5 with. The jimmy has a 350/700/3.73/31's combo. GVWR is 6100 according too the door. I've asked and told I should be fine, but can anyone help me with the math here, so I get that warm-fuzzy? Weight of tow truck: 4,839lbs GVWR: 6,100 Max weight of K5: 4,371 Some of the parts that go to it will be in the bed of the jimmy.... Car hauler: ~2,000lbs I've lied to UHAUL so far, saying I would be towing a 95 intrepid and they thought I'd be okay. I figured if I told them I was towing a k5 w/ a k5 they'd say they'd rather not rent too me... /forums/images/graemlins/doah.gif Please help!
