On XXX between 11 am to 2pm, I was driving [XXX] to [XXX], via [XXX], and at rest area [XXX], I stopped for fueling truck and getting something to eat with family. After stopping at the parking site for trailer, I noticed that the RV box on the front above the gooseneck, was touching the top of my truck trunk. I use a fifth wheel gooseneck and tow from the center of my truck/trunk bed, and we usually have about 2 inch gap between rv and truck, but at this time there was no gap, the weight of RV was on top the truck back side panels. The Lippert frame welds were broken. I have to call a 50 ton truck crane to tow RV to closest Camping World dealer at Fort Pierce. I was lucky that my 12,000 lb RV trailer did not disconnected, I could have killed my family in a hard brake, or someone in the highway if the trailer gets disconnected (the safety chains nor the emergency brake would have stop it to fall and rollover). My family (wife and kids) are psychologically affected and will not ride a truck towing and RV again, and I will not do either. I opened a claim with insurance Progressive (Claim#XXX), but they have denied any coverage saying manufacturer's defect are not covered by any policy. However they have failed to provide written report demonstrating it is defect. I opened Work Order #XXX, with the reseller, Camping World, but they have not being helpful, I left the RV at their parking lot and visit them in person to open my request for inspection and coverage, they refused to accept the RV inside their workshop, they told me I have to repair the weld first before they accept the unit. I opened claim with Lippert (trailer manufacturer), Case #XXX, they came back saying unit is not dafe to drive, and it is not a defect. On XXX called Keystone at [XXX], opened a complaint but did not get any case number, send pictures to [XXX], and they told me they are responsible.
