I just purchased a new 2017 Chevy Silverado 1500 double cab pickup with the standard bed. It has the 5.3 V8 and towing package with built in brake controller 4.3 axle. The GVWR is 72000. According to the manual it looks like I can tow a 9800lb trailer. I am looking at a trailer with a 8600lb GVWR. Can I safely tow this trailer? Never really understood how to figure what I can tow. Any help or advise appreciated.
No way the axle is 4.3 ... most likely GM's ubiquitous 3.42, not the best for towing, 'though the 6 speed narrow ratio transmission will help. No way GVWR is 72000 either ... guessing you mean 7200 lbs. I recently upgraded from my 2005 Avalanche to a 2012 Silverado Crew Cab 4x4, same 5.3L, same 3.42 axle ratio, same 6-spd transmission, but GVWR is 7000 lbs ... I wouldn't tow a trailer weighing any more than ~ 6000 lbs loaded & ready to camp with this truck.
If you
really want to understand what you can safely tow with your truck you want to weigh it with a full tank of gas. If you're in it at the time it's on the scales subtract your weight from the scale reading. The result is the truck's actual base weight as it sits there ready to be hitched to a trailer. Subtract that number from it's GVWR which is listed on the driver's side door jamb sticker and the result will be the truck's actual payload capacity which you'll use to account for the weight of all people and all cargo in the truck plus any tongue weight transferred from the trailer to the truck. Exceed that and you'll most likely exceed the truck's GRAWR (Gross Rear Axle Weight Rating) ... and count on it, you'll hit that wall l-o-n-g before you come anywhere near the truck's GCWR (Gross Combined Weight Rating).
Here's a sample of my own Trailer Tow Capacity Worksheet.
