Need some help from the experts here
. This Friday and today was the first extended trip (2.5 hours each way) with our 03 Chateau Sport 26Q weighing about 11,500lbs.
Last month I installed my valve extenders on my duals and found them to be at 90lbs (max should be 80) and dropped all 4 to max air. I have the fronts set at 75lbs. Never felt any shimmy or shake before this trip. I would only really notice it at 50+ mph. No affect on the front. Just made for an uncomfortable ride. We are leaving in 3 weeks for a 5 weeks trip and I want to fix this.
I was thinking that my rear duals may be out of balance or some other problem. Just need an idea of where to start.
