When we purchased our Precept 31UL last August after trading in a Melbourne, our first road trip was a total disaster. List is too long, but main issue is the overall handling and ride. Constant shaking, swaying, like riding in a school bus. Took to dealer they did an alignment and other adjustments. Thought everything was fine. Our last trip to Texas it appears that the issues stated above still exist. Can't even read a paper while sitting at the table because of the constant vibrations and the cabinets kept coming open. The cabinet with the TV in bedroom came open and all of the DVD's flew out!!! Went back to dealer and Jayco agreed to send us to a Ford Dealership in Texas to check the ride and the chassis. Overall conclusion, the length of this unit is to long for the wheel base. Jayco states that they do not "weld" any framing, but I learned that the frame from the back axle to the bumper is welded. Also if you stand in the bedroom and look out the front windshield the unit is very "back heavy" and the nose is slightly higher.
Bottom line, customer service basically is saying that because the chassis checked out fine then other issues are under warranty. I asked why so many people were adding safe-t-bars, etc. because purchasing something over $100,000. should have that already. Still waiting to hear back from them and BTW, they are putting all of the responsibility on my dealer!!!!
