In consideration of this thread and the ride quality, I have the same question(s) but more so on the towing ride quality. Not attempting to hijack the thread, but understand what others have done or suggest about towing ride quality.
I have a 2020 GMC Denali HD 6.6. The ride quality around town is not bad at all when I have the air pressure at 65R 55F with the stock GY tires on the 20in factory wheels. I am curious from others on the their ride quality when pulling a 5th wheel however. I own a large toy hauler and use a Reese Goosebox with the air ride option in the it. On smooth roads it is an amazing ride. When I pull down I-95 to Florida ,the road beats me to death in places (beats on the family more). I do have Tembren helper bump-stops, and the factory shocks. Wondering what could I do to help the ride quality when pulling my toy hauler or Horse trailer? I am running about 83-85 Pounds in the rear tires (hot) during pulling . I start them at about 76 Pounds, and by the time I am on I-95 they get up to 83-85... So I could start lower in the hopes they only get to 81 ish pounds, but that makes me super nervous to start them at 71-72 pounds. I have heard tons about swapping the Rancho's for the Bilstein 4600/5100 shocks, and am curious if anyone that has done that also pulls a heavy load and could tell the difference there. I would have to go buy shocks and replace mine that are still under warranty and not have it help at all. Thanks for your time and consideration in responding!
