I am experiencing symptoms, consistent with excessive frame movement and structural failure in my 42 foot fifth wheel toy hauler RV. We have been monitoring this for the time we have owned it just over six weeks and have noticed an increase and symptoms that research shows indicate there is a problem.. we are seeking professional inspection and guidance to establish the scope of it and hopefully catching it at the earlier side in order to hopefully deal with the issue easier than after a total failure. The symptoms include 1- the interior upper section horizontal lag bolts that hold the camper walls to the frame all had come loose completely. There were four on one side and five on the other. 2- the underside curved fillon panel by the pin box is ripple and curved, and shows movement 3- the left and right sides of the camper towards the front are becoming out of square with the rest of the camper and the seals around the doors are showing larger gaps and looking more out of square 4- interior doors and exterior doors of the camper are all experiencing difficulty latching and are becoming out of square to the original structure 5- there is a changing of the distance, measurements both in height, and in relation to the lower frame members from the pin box where the camper tows from. And what appears to be some twisting out of square. 6- front panel door is buckling in the center and will no longer close geometry of the opening has been compromised It is clear that we are experiencing frame structural failure between the area where the camper toast from in relation to the main frame of the camper
