So I recently went on a 500+ mile trip towing a 2300lb pop up and all the trimmings. We also had two adults and two kids. Did not get to weigh the truck with trailer, but can assume that we were loaded in excess of 3000-3500lbs all in. The truck towed great! Decent mileage 17.4mpg. At no point did it struggle or seem overloaded. What I did find lacking was the rear suspension. It was way too soft. We are now upgrading to a 3900lb airstream travel trailer. With a tongue weight of 520lbs. I am looking to stiffen the rear to help make up for that high tongue weight. I have been looking into air bags, (specifically ride rites) and Dakar leafs. In a perfect world I would like to go with a stiffer leaf. The problem I have with the Dakars is the lift. I want to keep my truck at stock height.
What have you guys done to make up for these soft stock leaf springs? Is their a stiffer spring that will not result in a higher than stock suspension? Or are ride rites the only solution?
Thank you in advance for all suggestions and comments.
