Thanks for all the posts, dang didnt know people went as high as some of you guys! Got this yesterday from a customer of mine he says its 33,640, trying to find out if that is Gross or not. He's going from FL to LA Its a stock 05 LLY with only an LBZ turbo inlet and airbox upgrade. Says he's crusing at 70, that old bastard is nuts hope he makes it back home, might need to see Mike after this one...
That is gross combined weight
That's like towing a barn. Hope he has an EGT gauge.
