The difference in average quality of build between any RV brand is negligible. So much is hand assembled compared to say the automotive industry where automation improves quality and consistency. There is some variance in quality of materials and design between brands, but that is each person's preference. You will find horror stories about any brand. If you are willing to learn and perform the regular inspections and maintenance, then pick your favorite. Warranties expire after one or two short camping seasons. You then are then on our own or making trips to the dealer for every little thing.
