Really? I'm amazed. Well, it seems the engine / drivetrain is hefty enough to take it, although 50 mph on the 75 mph Interstate 40 would make me a big fat green target for some half asleep long haul trucker. 7 to 8 MPG..my Avalanche with the 6500 engine package only gets 10, considering the 15,000 lb truck the M35A2 is that's not terrible. I'm assuming this is all running commercial pump diesel?

My other question, and getting out of Colorado this one is important...how do your BRAKES hold up in the mountains? The stretch of Highway I-25 starting at just south of Walsenburg Co.all the way to Santa Fe, New Mexico has a couple of very hairy 6% grade downhills..this is a big truck with old school shoe brakes..who's got some good brake stories for me?
