Maybe someone can help me, I have a 2001 Chevy 2500 suburban with an 8.1L v8 It has all the bells and whistles. I tow a 1999 31ft. travel trailer that is around 9000 lbs. The Ride control light is on again after I had the passanger side replaced and when I tow the truck is all over the road. i have the trailer hitch on wright as per the instructions. Maybe some can shed some light on something thanks
