What Is the Risk Of Towing At Maximum Capacity

Question

Question:

I have a 2009 yukon xl denali rated for 7900 lbs. The flagstaff travel trailer Im looking at weighs in at right around 7060 lbs, leaving me 840 lbs of gear and bodies if i understand correctly. Do i need to look for something smaller? 2 adults, 4 kids and a dog will eat up most of that 900 lbs. Answers seem to be all over the place, everyone is an expert. The general watercooler consensus is yeah you can pull it, but it might struggle up hill. So in short, do i need to allot myself 1300, 1500, 1800 lbs? for family camping? Or will the denali prob be ok?

The answer to your question is yes, As long as you are under the specified weight limit of your vehicle's maximum towing capacity and maximum tongue weight rating, then you can physically tow the trailer. The max tongue weight for your 2009 GMC Yukon Denali is 600 lbs. without a weight distribution system and 1,100 lbs. with a weight distribution system.

To be sure you are not exceeding the weight capacity of the vehicle with your loaded ready to tow trailer with all additions included, you can take this setup to a nearby weight station for an exact calculation.

However, as a general rule of thumb, it is not ideal to be at the very top end of your vehicle's weight capacity as this will further strain the vehicle's suspension and components wear life.

If you do decide to tow the trailer with your Denali, I strongly recommend the use of a larger transmission cooler in addition to a weight distribution system or rear suspension enhancements such as the Equal-i-zer weight distribution system, Firestone airbags or upgraded Timbren bump stops. Suspension kits may help level the vehicle however will not add towing capacity.

I have included a review video of the Equal-i-zer weight distribution system, Timbren stops and Firestone air bags for you.

The reason that 10 Gauge #10-1-1 or 12 Gauge #12-1-1 wire is recommended for 10" brake assemblies, like part #AKEBRK-35-SA, is because they pull more power than the lights on your trailer. I believe the green wire you are referring to carries…
