I pulled my sisters trailer when their truck broke down and loaded it is 7700 lbs which is well within...

I have a 2021 Sierra Elevation and really needing to get pure details on my towing capabilities. The dealer did not seem to want to help. I realize you should not tow the complete allowance. All good there. I just need to find my exact capabilities. We are debating on going to a very light...

So I am about to puchase a 2013 GMC Yukon SLT with a "towing package". Depending on which source I use the tow rating ranges from 5,000 lbs on up. Two questions: 1. What is the actual tow rating? 2. Can I tow a 4,000 lb RV tow behind trailer at 65 mph or so? My current vehicle struggles above...

I have a 2015 GMC Sierra HD 3500 Denali diesel that will not maintain RPM nor shift from 4th to 3rd gear when towing a heavy load up hills. Speed will decrease until about 40 mph before it will shift. I've had similiar GMC trucks for 18 years, towing basically the same type of load. Never had...

Ok, so i bought this thing at an auction for a great price with around 156000 miles. Since then It now has 182000. I recently acquired an 18' tandem trailer weighing about 3000lbs to pull my derby car with (for a total of about 5000lbs). I can get the car over the axles and off the tongue, but...

I recently bought a 2013 Yukon XL SLT 4WD and was VERY disappointed to learn it is only rated for 5000 lb towing capacity. I would have bought a Tacoma if I wanted to only tow 5000 lbs. I have talked to GMC directly and 3 dealerships and according to the experts it is "impossible" to increase...

Hope someone can help me make a good decision. I am ready to pull the trigger on a new 2014 Sierra SLT. I will pull a large trailer once or twice a week at most. Trailer loaded will reach 9000 lbs +/-. The only rear axle ratio available is the 3.42. Can this truck handle this trailer on a...

Hello all! I'm new to this forum, but have been a GMC owner for many years. Here is my current issue: I have a 1999 Yukon 1500. I'm considering buying a boat that would bring my trailer weight to about 7000 lbs. Then I have to put the family in the Yukon. According to my manual, which is...

I recently bought the above with 122,000 miles to tow a 33 foot fifth wheel travel trailer. It does that job, but I feel it could do a better job. Anyone have any suggestions on what I could do to improve towing torque for a reasonable, under 1k, price. If this also helped mpg, that would be...
