Bought my first keystone 5th wheel, always have been a Forest River fan...still am, keystone warranty and customer service is terrible!! Radius metal under the roof membrane wasn’t installed properly according to 2 dealers “extremely poor manufacturing QC”. Metal not secured well or adhered to the substrate, metal is damaging the roof membrane. Roof is under warranty, coach is not (only 2 years old), coach is causing the damage so “you’re SOL”!! 100k coach!! Keystone is TERRIBLE!!
