I understand the average life expectancy for an RV trailer is about 10 years. That is really pathetic since many RVs don't have that much use. The industry is well known for poor engineering, poor design and poor quality of construction. Many tailers barely have enough capacity to carry more than a few hundred pounds over the base weight. You can blame the customer for not understanding and overloading. I am more inclined to blame the maker for cutting corners. Water intrusion is another major cause of failure. Again, you can blame the customer for lack of maintenance. I blame the manufacturer. Construction is often so poor that seams are sure to open up due to twisting and vibrations while driving. The customer certainly has a part in this by not doing the homework and buying based on dreams and surface appearance.
Some RVs are indeed fairly well designed and built to last. Unfortunately that seems to be the exception.
