Duramax van mileage

I can't help with the van mileage, but I can tell you what my mileage on 2 Chevy Crew Cab Long Bed Duramax Dually with Allison transmissions and 3.73 rear ends has been.

'01 2 wheel drive (5 speed Allison)

17.58 mpg for 59,038 solo miles (most highway driving at 65 mph) 9.65 mpg for 36,592 towing miles (most highway driving at 65 mph) with a 5th wheel weighing about 14,000 pounds.

'06 4 wheel drive (6 speed Allison)

17.50 mpg for 13,219 solo miles (most highway driving 60-65 mph) 10.19 mpg for 3,831 towing miles (most highway driving at 65 mph) with a 5th wheel weighing about 14,000 pounds. 8.97 mpg for 3,019 towing miles (most highway driving at 65 mph) with a 5th wheel weighing about 15,700 pounds.

The '06 isn't really broken in yet and the mileage is still going up. We just returned from 2 months in Montana where I drove 6,654 solo miles and averaged 19.05 mpg.

Hope this helps.

Your mileage while towing seems very low for oil burners! I get between 8 MPG and 9.5 MPG towing our 32' fifth-wheel w/ slideout using an '02 2500HD crew cab long box 4WD 4.10 w/ the 8.1L gas and Allison!

Your truck is a lot lighter than my 3500 and your trailer is a lot smaller/lighter. To pharase it the way you did, I get between 7.00 and

11.52 mpg. All depends if I am mostly going up hill, down hill, with the wind or against it. It takes about 25,000 miles to 'break in' a diesel and I don't have that many miles on it yet.

Personally I would drop the Sprinter off any list. They have been so bad with the front brakes and front hub assemblies failing I wouldn't even look at one.

I am presently running a 2000 Chev HD 2500 old style body 2WD pickup with

5.7, 4L80E, 3.73 gears and I get 17.5 unloaded, 12 mpg with the tandem axle cargo trailer and topper and 9-10 mpg with pop up camper and the trailer. What got me thinking about a van is the mileage the Dodge literature is claiming, anywhere from 21 to 30 depending on configuration. Also the fact that once my camper is set up it takes 20 min to tear down for a trip to get supplies. I have heard about other problems with the Sprinter from my FedEx driver including complaints about the rear door hinges failing and rattles on rough roads. With the Chevy I would have to opt for a cargo box installed by the aftermarket in order to get the height to be able to stand up in the van. I find it curious that option isn't offered by GM.

Thanks for the info guys! Steve
