I currently drive a 2008 chevy silverado c/c w/ 5.3 , 3.73 w/ factory towing equipment and trailering suspension. I have researched until I am blue in the face trying to make the right decision on a new tt. This truck according to GM and the vin has the suspension and equipment to tow 7600 lbs safely with a combined weight rating of 13k. That being said, I am considering a jayco fthr. exp 213, dry 4260, maxed 5500, on paper I should be more than ok. I pulled an equation from this site and factored the truck, fuel load, family and other gear and come in at just a shade over 11000 lbs total for everything and it put me into that 10% range, actually closer to 15%. I am not new to towing and pulling but I am looking for other opinions concerning this set up, I realize that the factory numbers are averages but just how far off are they is the question ? Has anyone got anything similar that can vouch for this truck with this size load and it's overall performance ? Am I going to be forced into third gear the entire trip or will the tow/haul mode be sufficient ?
