2016 crewcab, 4x4 short bed, loaded with 2 adults, 3 kids and 300lbs in bed. Travel Trailer: dual axel with 7000lb loaded, Tongue weight loaded probably 700lbs. WDH Anderson, adjusted and tight. Trailer sits balanced back front to back.. CAT scale: truck front and back axles loaded equally (3550 lbs each). This set up worked great before. BUT: last trip, it got to be very windy. Trailer back end would sway. Truck felt stable mostly, but seeing trailer swaying does get your attentions. Had to slow down to 45 MPH just to control it. So the question is: only thing i can think of to improve is some air bags/ support bump stops to get little better control in rear end. When loaded, the truck does sit on the stock bump stops, and it does feel harsh when loaded truck hits bumps. Would you spend another 400 dollars to make it work? Or give up and go to 2500? Thank you for advice.
