Oh, and I forgot to point out my ART built stretched Mega Cab Dodge Dually hauler...
biggest thing I hated about it was the short box so I had the frame stretched 2 feet and a long box dropped on it... long as hell but perfect for going down the road, super smooth!
ART did a full build on the truck so there are no issues with hauling well over 80 if you want to
Central Frame in Waco did the stretch and is even covered by a 36000 mile warranty, it looks so good you would swear it is factory...
