Wow that thing is bad ass. Sad thing is it gets the same mpg as my truck empty while he is pulling a camper
I know the Cat is the weak point. Just thinking the body and frame, plus something like the 7.8L Isuzu that they put in the 6500's and up. I saw several of those when looking around last night. I think i even saw one for about $3,500.
Originally saw this one, and its in Indiana. http://www.truckpaper.com/listings/trucks/for-sale/7180031/1994-gmc-topkick-lo-pro
With a slight repower, and a few creature comfort upgrades, this would be the talk of the scene.
