We bought a Thor ACE 30.4 in 2018 at the Hershey RV show. We picked up the coach in February 2018. We’ve used it quite a bit over the last three years and really enjoy the coach.
This summer we began noticing bumps under the wallpaper on the wall board next to the driver seat.
At the end of the season, I brought the unit in to be winterized and take care of some maintenance. As I sat in the driver seat I noticed a “mushroom“ protruding out of the wall next to the driver seat.
My repair guy took the wallboard off and found extensive water damage inside the wall causing corrosion to all the wood under the window.
As a very experienced motorcoach and trailer mechanic, maintenance and repair person, he believes the water was coming in through a channel that covers the seam in the fiberglass on the front side of the window. That channel is a hollow track that runs from the roof down to the top of the window. In the manufacturing process, Thor attaches the channel and then inserts the window crushing the end of the channel between the window and the siding. They then seal the window. This leaves a “gutter” that water can travel from the roof directly inside the window.
I have seen many others who own a Thor ACE who have had similar problems. This indicates that it’s a manufacturing defect. After many emails from myself and my repair shop (who was ignored), Thor does not agree and is taking no responsibility for the repair work. I’m posting this as a heads up to others who may have a similar situation with their coaches. If you do have bumps under the wallpaper, have it checked carefully. Thor should stand by their product when issues such as these occur and are defects in the manufacturing process. See pictures below.
