I'm interested in the same setup.Maybe diesel though.Does anyone have pics of their setups with this type of truck?

I don't think you will get much better than a 3500 Chev dually you actually prolly get less because the Isuzu's are lower geared. When you think of it a 350 trying to propel a 15,000lb gvw truck even Chevy didn't put 350s in the 3500HDs that had a 15,000lb gvw.

I think if you are after good fuel mileage you should stick with the trucks with the diesel sure they are a little underpowered but atleast you will get better than 8 mpg.

I second your post about American Diesels. I have two Isuzu cab overs diesels and get 12 MPG on both running empty. In the mean time my buddies with the 7.3 diesels are getting 19 and 20 MPG with the magic adjustable computer box. They also have more power and better performance. I like my Cab Overs set up, but as far as power, speed and MPG they suck.
