Maybe a 3/4ton avalanche is just what you need. Get 4.10 rear gears like me, and you can tow 12,000lbs. It depends on how much your going to use it, because like the old 454, the 496 gets the 'same' MPG loaded or empty. That means 11-12MPG I dont know maybe you cant handle that. Both of my duramaxes got a little less then 30mpg(not to mension Diesel is FREE at most of my job sites) My new not so loaded up one is only the extended cab, and not the crew cab like my last one.
