I have a 2003 GMC Sierra SLT 4x4 Ext Cab. I was looking at getting a 30' toy hauler but did not know which rear end I have on my truck. The owners manual states 2 different types. How can I determine which one I have?

Replying to: 3839 (Jun 06, 2009 8:25 am) To compare: My 496 (I refuse to go metric) pulls my 9500lb 5th wheel up a 6% or so hill around 45 mph. Maybe 50 if I push it and the hill is short. It's factory stock. And the Allison is a great transmission. |
