I feel your pain on the Chevy clearance issue. I used to build roads on Vancouver Island in BC. Most of the terrain is very rocky. As in reefs of rock, and a LOT of blasting required. The blasting company we work with will only buy Chevs. I would spend all day in a Komatsu 308 excavator cleaning off the rock for the drills, and then at the end of the day, I would have to put half of it back so the stoopit chebys could get out! I drove a Landcruiser wagon and the SMART driller who refused to drive a chev and bought his own F350 would drive out of the bush no problem. Then comes the radio call "Help! our chevs can't get out! Come back and build us ramps so we don't bottom-out" What a pain in the butt!
