What we're looking to validate here is the convenience and easiness of towing with the Chevy Avalanche. This kind of evaluation is a complement to our regular road tests. Our tester was a base 2007 Avalanche LS with 4-wheel drive; its FlexFuel Vortec 5.3-litre V8 engine runs on gasoline or E85 and is mated to a 4-speed automatic transmission.
