Hey, this is Dave in Spartanburg, SC. I have a 2010 Avalanche LTZ, 4x4, pearl paint with black leather. 55k miles. I pull a mostly original 1967 Airstream Land Yacht Overlander with it. Been in the family since 1969. I am in the process of swapping out my cracked dash with a home brew - reinforced new one. Looking for info on gearing and trans temp management for towing but will post that in appropriate forum. Peace
