First, I want to say that I am not planning on exceeding my towing limits with my 2010 Eddie Bauer. I am planning on pulling a 20' enclosed trailer behind my truck and I am looking for ways to improve its performance for this type of duty and not really impact its day to day. The truck has the full towing package, everything is fresh as the truck has less than 30,000 miles on it. I have been pulling an 18foot open trailer for years with my race car on it and I don't even notice its there. I use load leveling loading bars, plus I am also looking at adding a sway control device to try to control sway. I am also looking at adding an SCT or similar engine and transmission controller. What I am looking for are other ways to stabilize the suspension and improve its ability to tow at reasonable speeds. Ideas?
