Yes, our W350 Dodge Crew cab 4x4 gets 10 and sits in the garage unless we need to buck snowdrifts. Meanwhile the LT1 Trans Am gets 24MPG we drive it as much as possible, it is not a garage queen. I work with a guy that has a late 2000 corvette that averages in the high 20s no matter how he drives it. He’s driven it in snow!
My 2008 Suburban gets around 17-19 highway on 100% gas I can still get at the Coop.
On E-85, that drops to around 14, and completely blows in city driving.
Haven’t been able to find a hybrid capable of towing 7,500lbs up hill in the snow.
