Make sure you pull both rear brake/taillight assemblies on any new Thor coach. The Vegas, Axis, and class C coaches use the same assembly. The foam tail-light to body gasket is very thin, and it leaks. I removed my tail-light to replace a burned-out brake lamp, and discovered water intrusion into the cavity and inside the plywood substrate and finish fiberglass skin. The plywood was already beginning to rot and was saturated, after only 4 months. I dried out both tail-light cavities, and re-sealed with good quality silicone. It is imperative that you check this because total delamination of the rear wall will occur in a very short time. I do believe I caught this design flaw early enough so that the plywood will dry out, and delamination was stopped. This type of flaw is unforgivable in a modern coach, and is due to hurried construction, poor quality components, and a total lack of water intrusion knowledge at the coach design level.
