We have a 2017 Thor Aria 3901 and had few issues like yours as well. Just not quite as many. One of the ways we rectified our. Coach issues was to have it completely inspected. After the inspection, we identified the issues that were covered by the warranty and had them corrected . We had a leak in hot water line from the water heater, leak behind the washer, inoperative dash AC Unit, loose right side rear view mirror. If you would like more insight on what we did to correct our unit just respond to this post and I will provide a contact number for you. Once you get your issue fixed you will truly enjoy your coach. We love ours but it didn’t come without a few challenges the beginning.
