2014 HEARTLAND BIGHORN Complaints

I have videos of my immaculate 2014 3570Fifth Wheel. Went to wire a set of stabilizer jacks and this is what I found. It is not the only truss under my RV that has welding on the cross braces or web that has failed. vin number [XXX]. My welder said the bad welds started to fail and cascade along the truss. This is a disaster! We need to continue removing the under covering and inspect the rest of the frame. This should never have happened! It appears the truss was tack welded and left in an area where moisture collected on the welding and started the corrosion process prior to assembly of the RV. The 1st video shows Two broken, rusted welds on the diagonal braces. The adjacent braces are now buckling. The next step would be the fracturing of the braces at the buckle. The second video shows the aftermath of the failure process. This failure of the trusses destabilizes the frame, removes support for the floor. The damage is hidden by the protective under carriage covering and was discovered XXX Symptoms we have noticed are sinking floor, sponge floor and metal to metal squeaks when leaving or entering the RV and going over speed bumps at slow speeds.
