We toured several plants last year. Many use Lippert standard designed frames and design their rigs around the frame. Companies like Jayco, KZ and Open Range on the other hand design the entire rig including the frame. Lippert builds to their design. We were told at both Jayco and KZ that the frames being built by Lippert are the same designs that were built by Leyland...no difference. And yes they do inspect the frames BEFORE using them. We saw a Lippert mobile service truck at KZ and Open Range rewelding joints and even adding or moving braces either not installed or slightly off. A lot depends on the RV manufacturer for the total quality. Anyone can and will make mistakes.
