Towing 7500 lbs with a 2006 5.3L Silvy? ... thanks for my morning chuckle. :W Funny now, but not so much if you actually attempt it ... first tow and you'll be wondering what the heck you were thinking. :R No way, no how is this truck suitable for towing any more than ~ 6000 lbs fully loaded, particularly if it's running GM's ubiquitous non-tow friendly 3.42 axle. Having towed our 5500 lb (fully loaded) KZ Spree for 4 yrs with this same truck over just about every terrain one might encounter I wouldn't have wanted to tow any more. I replaced that truck with an Avalanche - same engine, same wide ratio 4-spd transmission that isn't anywhere near as capable as the current narrow ratio 6-spd, and same non-tow friendly 3.42 axle ratio. Our current trailer is 1000 lbs lighter, ~ 4500 lbs loaded and ready to camp, and even though my passenger load is lighter because it's now just my wife and I our Av does just OK and certainly wouldn't set any land speed records. Towing 7500 lbs? - not a chance. Not only is there insufficient grunt under the hood for this size of trailer but you'll run out of sufficient payload capacity to account for trailer tongue weight transferred to the truck l-o-n-g before you get anywhere near the truck's GCWR. Prove it to yourself - fill the truck tank, mount weight distribution including spring bars, and go weigh it. Subtract your weight from the scale reading and you'll have your particular truck's dead weight as it's sits there ready to be hitched to a trailer. Subtract that number from it's GVWR and you'll have it's actual, real world payload capacity ... and it won't be anywhere near 1500 lbs, guaranteed. Believe otherwise and you're dreaming. ;)

Well thanks for the uneducated response..
"Uneducated"? Ha Ha ... now that's funny, for all the reasons I already detailed in my post. :R Hey, do what you want but no degree of trucking experience on your part will change the facts of the matter - 6000 lbs total trailer weight is about as much as you should expect to tow with your older 5.3L gas aspirated GM coupled to the older wide ratio 4-spd transmission which in turn is running GM's non tow friendly 3.42 axle ratio. By hey, go ahead, tow more and find out the hard way just how poor the tow will be. :W
