I NEED to improve The suspension on my 2006 Duramax short bed pick up. I pull a 30 foot fifth wheel RV. Returning on interstate 25 in Colorado recently it felt like I was riding in a Hay wagon. I won’t mention how the pot money here in Colorado hasn’t improved the roads whatsoever but thats another discussion. I really feel like there should be something I can do to improve this ride. Also my wife has a pacemaker that’s activated by motion and just riding in the truck had her heart rate increasing to over 120 bpm… Very uncomfortable for her. I wanna make this truck last but I need reliable information on how I can improve the ride. Thanks in advance for any information you guys can provide.
