Its the Cougar 27RESWE so its about a 29' trailer in total. The truck had the 6.2l with 10 speed. I say had, because after crunching the numbers, with truck, canopy, passengers, dogs and trailer tongue weight I was about 500-600lbs over the payload of the truck as it did not have the HD package. Long story. We took it from our home in Oregon to Flathead Lake in Montana and the truck had no issue towing the setup, I am just a worry wort, and didn't want to give the insurance CO any reason to deny a claim should anything happen. Stepped up to a 2020 2500 Denali. So that setup was do able, just not for me.
