Suspension Issue?
I have a 2013 Sierra 38' fifth wheel. I have lost 3 tires due to complete tread separation in 4 years. I thought originally that I had a load rating (E) tire problem. However, after replacing all 5 ti...

Sorry for the delay in this posting. It has been quite an experience. I'll list the steps below:
1. Dealer found the tires were out of alignment due to wrong position of a hanger. Solution was to remove and re-hang the hanger in the correct position. The dealer decided to get someone from Sierra to reposition the hanger.
2. Sierra tech came to dealer and found another problem. The rear axle was bent and he couldn't go any farther. He said either I hit something in the road or it was caused be the nose being to high. Anyone have their nose to high? He also said there was no bottoming of the wheels to the chassis. Don't believe that one from the evidence on the other side.
3. So the final solution was to completely replace the suspension. New hangers, axles, leaf springs, equilizer and Correctrack system for alignment. They also added a 2 inch square bar along the chassis which added 2 inches to the height. (was this also to prevent bottoming of the tires to the chassis)? They also added 3 more 2 inch bars across the width for stability.
This entire process took 5 months. Took it in mid September 2017 and got it back mid February 2018. So with the 2 inch bars and the Correctrack the RV is now 4 inches higher which helps some of the ride issue because of the nose being higher than the rear.
I've only been able to take one short trip so far (500 - 600 mi total). Ride is greatly improved but still have some rough rides on bumps. Still would like to lower the nose a bit more. Maybe another 2-3 inches. Might need to lower the truck to accomplish this.
