Welcome and congratulations. I love my Challenger but of course it is an RV and nothing is perfect. I also had the same shower leak which should be easily fixed by re-caulking with clear seal. Start building a warranty list and be sure keep in contact with both your dealer and Thor Warranty directly. I have heard stories of dealers failing people but Thor Warranty has been nothing but spectacular so far and that is who I deal with directly.
There are a lot of great and very k knowledgeable Challenger owners on here and RVillage.com so definitely keep in contact and we can learn from each other and make our Rv experiences that much better.
