Just bought a 21' pontoon that when I go thru a curve it feels like it is trying to push the back end of My bronco around or is causing it to dip. Hard to explain. Am I looking at worn out shocks, Need to upgrade the rear sway bar, Need to add a leaf to the rear springs, A six inch lift with some 35 inch BFG's!lol I had a 17ft center console that weighed about the same and had no problems. I think it is a balance issue on the trailer but can't afford a $2000 tandem axle. Any help or suggestions That I could do to the truck to solve this issue would be greatly appreciated.
