#232 of 303 Sierra unable to meet posted towing capacity
Jun 23, 2010 (3:21 pm)
Just purchased a 2010 Sierra 1500 Z71 and was advised that it could tow up to 9700 pounds. First trip out, I discovered the truck is unable to handle my trailer that has a dry weight of 7500 pounds and do not exceed 8500 pounds gross. Unable to exceed 50 miles an hour due to excessive swaying and has been advised by the RV dealer to park the trailer due to a safety hazzard. The RV dealer has checked out the trailer, hitch and all attachments with no issues. The GMC dealer checked out the suspension and found no problems either and then suggested a tire upgrade, done that with 10 plys but did not help. Now they are suggesting air bags??? To be installed tomorrow. They also advised me that I was the first case reported but now learning it may be a common problem with the new models. Older models with the same specs as mine, tow the trailer fine. Wondering how common is this problem and looking for suggestions on how to rectify my problem.

Do you have an equalizer hitch? What's the tongue weight on the trailer and max allowable tongue weight for the truck?

The hitch is a Reese with 1200 pound bars and I'm using the dual cam sway control. The tongue weight of the trailer (Jasper Trail 29RKS) is 748 pounds empty. The tongue weight for the truck with weight distribution is 1100.

Are the truck and trailer level when the equalizer hitch is connected? Can't thank of any other reason for it to have such a large sway problem. 750 pounds is a lot of tongue weight. Good luck

Even though the trailer is within GM's posted weights of 9600 pounds for trailer capacity (7538), and 1100 tongue weight ( 748) it has been concluded by some GM staff, the RV dealership and other professionals the truck is unable to safely tow my trailer. At this point, my only option now is to downsize the trailer...has not been a great week. Vehicle was purchased based on online searches, GM specifications, discussions with persons who own vehicles 2007 and older and four different GM salesmen at different dealerships. All advised the truck could tow the trailer. Great truck for a car, but I wanted a truck...strange two older models with lower posted towing capacities than mine could tow the trailer without a problem, the 2009's and 10's not a chance. I have exhauted all avenues with the GM dealership and I am stuck with a truck that I wish otherwise. Fortunately for me, the RV dealer came through and gave me a full refund and offered a new downsized trailer whick I have accepted. I am hearing horror stories oll over the province similiar to mine. From suggestions from various GM staff I ungraded tires, installed air bags, and done everthig possible with leveling and several other changes for the past three weeks...all at my expense with one execption, the dealer installed the air bags I purchased. Anybody out there having the same delemma?

Sorry to hear that Coveman. I upgraded my trailer and truck last year. I used to have a 2003 Chevy 1/2 ton ext cab. Now we have a 2009 Ford F150. It pulls our NRG Toy Hauler all over and up and down the biggest mountains with ease. I live in Montana and we have big hills. I installed air bags. Sure wish GM would get with the program. I loved my Chevy truck. BTW, I wanted to buy a new Chevy but couldn't get a 1/2 ton that would pull the trailer.

I hear you, if I did not need the truck for heavy duty towing, I would love my Sierra too. I sure wish GM produced a 1500 model that retained the older models towing capabilities. Ironically, one of the older trucks I used to sucessfully tow the trailer was a 2003 chevy, great truck. As soon as I can, I plan to unload the GM and possibly get a Ford as well. Hear they are getting great mileage and have great towing abilities, they appear to have come a long way over the past couple years.

Today my dealer installed new rear leaf springs (under warranty) which made a remarkable positive change to the overall performance to the truck. Apparently the truck was rust proofed and the dealer is suspecting this to be the cause of rubber/bushing failure in the springs.....similiar local experiences are being acknowledged with other GM' trucks as well as trucks from other dealers. Interesting. Not sure if this will address my towing issues until I give it a go in a few weeks but right now it sure is looking good. Will advise.
