Thanks Dave and Gary; I have looked at both motors and to me they look the same.
The 6.0 just has about 38 more cubic inches. My truck has the good tow package
with a lower range in the trany and a bigger radiator it just does not have the Hi and low 4X4.
I am just looking for a little extra power to clime the big mountains out here.
The pick up truck may have a little higher gear but there is not much differance.
The springs are the main differance I think, but I also load my trailer heavier on the
rear so as not to put the weight on the back of the suburban.
The thing is rated to pull 7,800 pounds but I try to keep it about 6,000.
Most of the 2500 chevy's are 4X4 so thats why the eat up so much fuel.
I took one on a test drive and it was very stiff and when I checked the
milage it was getting 12MPG. Mine gets 18 to 20 MPG. with syntec oil in it.
Also some of the 2500's come with a 8.1 too.
Kurt
