07 GMC Sierra Towing Question
I need some advice. I have a 2007 GMC Sierra 1500 Crew cab. It's the new body style, SLE1 package. It has a 4.8 liter and 3.42 rear axle ratio. The maximum trailer weight is 5400 lbs for my truck. Short of getting a new truck, what can I do to increase the towing capacity? Thanks for any advice.
