I have a W-4 Chevy. It is a cabover. This is a really nice little truck. I have the vortec 350 gas and automatic in mine but it also comes with a diesel and a stick. The main reason I went with this truck was that the GVW was about the same as a 3500, but the bed length was a lot longer (At 14 feet it is 4 feet at least) and turning radius was a lot smaller (turns shorter than any pickup i have owned, and i have owned a lot of those). I have owned it for 3 years now and really like the truck. Sunday I loaded 3 tons of fertilzer on the bed, a 2500# trailer with a 3500# tractor and a 1000# utility vehicle on it and it pulled just like it was unloaded. This is a nice little truck and the price was cheaper at the time, don't know about now. has a/c and a radio too!
