When I looked at a Bigfoot Super C. One thing that caught my attention was fuel tank size. It was smaller than the 80 gallon tank in most Chevy Super C’s. One other item was access to cab from living area. All other manufacturers has a cutout to give access to cab. Beyond those items I liked the layout.
Depending on when this 2007 was built. It may have the LBZ engine. After 2007.5 they had LMM with DPF with 6 speed transmission. My preference would be the LBZ. It can get a program update for 6 speed.
Hope this one is what you want in a Super C.
