"I had the truck about 14 months now. The truck tows our 38' 5th wheel nicely. I get between 8.8 to 11 MPG while towing, depending on my speed. I get close to 19 MPG not towing on the highway. The Diesel/Allison on this truck are great. I had a 1999 F350 Ford for 10 years-good truck also. It was a V-10 and I got 6-8MPG depending on speed while twoing. Non towing I got 10 MPG. I sold it with 150,000 on it and the engine and tranny were still in great shape. Right now I believe the GM has the better overalll package ,however the 2011 Ford F3500 with the new diesel might give the Chevy a run for its money."
"I bought my 2008 Chevy 1 ton crew cab dually brand new over a year ago. Put over 30K miles in first year, it never missed a beat. Pulled many a heavy loads, through the hills and down the highway. I am a very proud owner. The company I work for purchased one just like it at the same time, it has over 80K on it already, just a workaholic. Will definately buy another. Down falls not much could use a bigger fuel tank or an auxillary tank. I hate stoping for gas."
"I bought the duramax diesel. This truck is fun to drive and has tons of power. I've owned several late model trucks (both diesel and gas) in recent years, but this is far and away my favorite. I was at the dealer the other day (just an oil change) and the manager asked if I was ready to trade in. For the first time ever, I said "no way, what for?" I used to buy a new truck every model year, but this one will be with me several more years."
