[Kelly] We have a 1999 Chevy Suburban 1500. We have a draw tight hitch with equilizer bars and a sway bar. We also have electic brake controller. We pull a 98 Springdale lite 26 ft. travel trailer. It's dry weight is about 4400 lbs. Are there any other modifications that should be made to the suburban to keep it from getting damaged? It does have a 350 engine.
