Hey there everyone, I’m new here. Just trying to contribute a bit. I tow. 30’ ToyHauler with my TRX. It tows just fine As long as your gas mileage isn’t a problem for you. I got along 10mcg. The trailer is just under 7000lbs empty. I’m guessing around 9000lbs loaded. Maybe more. IMO, airbags are the wrong approach. They don’t distribute the weight any and only add more weight to the rear of the truck which will impact handling. You would do much better with a Load Distribution Hitch. I have a Husky version and it will decrease the sag in the rear to 1/2“ lower than the front when applied correctly. The handling is much better this way as well. Good luck.
