I use this primarily to haul a slide-in
camper, and after some mods, it
performs this task well. Weakest point
is brakes. I'm on my 3rd front and 2nd
rear set at 30K miles. They work well,
but don't last many miles. With a 454
V8, 4.10 rear end, and automatic trans,
I get 9-10 MPG. It is a great family
hauler, and the 4WD has saved me twice
from getting stuck and needing a tow.
Mods I did were additional rear helper
springs, air suspension, Bilstein
shocks, and load range G rear tires
(Goodyear). I do NOT have dual rear
I have a 1998 Sierra 3500 Dually 4wd. Last time I changed the distributor cap and rotor it was an 8 - 10 hour thing, because the cap is under the intake manifold so it is very difficult to tighten one...
