When it comes to General Motors products, is the flex-fuel benefit for real?
No. There’s not enough distribution, there’s not enough volume to bring the fuel price down, and there’s not enough efficiency to make the hassle worthwhile. For a large gas guzzler like the 2007 Chevrolet Avalanche, how many miles you get per tank is the most important thing – and don’t forget Osama and the polar bears, too. With E85, you get less mileage than with regular unleaded, you don’t really lower your monthly payment to the Middle East, and the poor bears will still swim around, looking for ice.

Is it easy to turn the 2007 Chevrolet Avalanche into a full-sized truck?
With a turn here and a click there, the Avalanche’s midgate can be easily removed to expand the length of the cargo bed. Perhaps the only real issue is the weight of the optional tonneau panels – don’t drop one of these on your toes.

What are the best and worst things about the 2007 Chevrolet Avalanche?
Easily, fuel economy is the worst thing about the new Avalanche. Prepare to pay at the pump for driving this vehicle around. Its best attribute is flexibility: with the same interior as the new Chevrolet Tahoe/Suburban, the Avalanche rides, tows, and hauls just like an SUV – but offers a truck bed big enough to handle just about anything.
