Hello everyone, newbie/first post here. I have been reading the forums, searching the internet, and called my local Chevy dealership and I am still confused on what exactly my truck will pull. I hope you fine people can help. I have a 2006 Chevy Silverado K1500 Extended Cab Short Box (6'6" box) 4WD, with a 5.3L engine, factory installed tow package with tranny cooler. The Axle ratio is 3.42. According to my truck manual the maximum trailer weight is 7700 LBS for fifth wheel or gooseneck. And trailer tongue weight should be 10 to 15 percent of total loaded trailer weight up to 1200 lbs on models with NHT Enhanced Trailering Performance. The GCWR is 13000 lbs. So is this 7700 lbs max trailer weight the same as GVWR? I am confused because my truck manual does not use the term GVWR. I have found a 5th wheel that has a dry weight of 7102 lbs, a GVWR of 11706, and a hitch weight of 1546 lbs. Will my truck safely pull this trailer? If it's not what will my truck pull? I would like to get a 5th wheel but if I'm too limited I may have get a TT. So that brings up another question, how heavy of a tow trailer can I get? Thanks in advance to everyone who responds.
