I purchased a 1990 Seabreeze about a year ago and I'm rebuilding the entire interior to enlarge the shower and reinforce all the cabinet attachments and secure the base cabs to the floor as the years of road vibration and lack of owner knowledge has taken its toll from neglect. I have industry knowledge myself to do all this and have built from scratch several RV's thru the years. I have owned 4 Toyota 1-ton chassis trucks I used in my repair business in Arizona and never experienced the rear end jolt I'm getting with the Seabreeze. RV rides fine, no sway, no control problems, no steering issues, just a jolt from every crack, bump, or irregularity in the pavement--at every speed as if there were no shocks at all. motorhome has factory springs, airlifts (holding air just fine) and shocks look newer. currently have unloaded interior so rear tires (like new and only a couple of years old) are at 45 lbs and airbags at 40 lbs--still a jolt every crack. Do you think this is spring, shock or both --or neither, sure need some input, anyone else with similar issues?
