Carpet has mushrooms growing along wall

Thank you, we will look into the fans and the dehumidifiers for the inside. This has been very helpful for us to get suggestions. Just to clarify my remarks above, for Wyoming.....we love that the cupboards and doors are solid and they do not fly open when going down the road like one of our former RV's did, these are very solid and high quality wood. I think the ill fitting door and the leaky outside compartment and such were just things that sometimes you will find on an RV. We deal with regular stuff just fine. But I was shocked to have a plant growing on my carpet!!! Over the years I have found we have come to despise a rubber roof, carpet and the dining tables with loose chairs. We love a booth. This RV has been a lesson for us. But you can't beat the size and you can't beat the maneuvering and ease of driving and parking. We will always have an A and a walk around Queen bed, and this was exactly what we were looking for. There will always be things that come up. We clearly need to be on top of all the maintenance even moreso. Weather is very hard on these things in Michigan. Mechanically we have had no other issues with the RV and it might be something we would consider getting if you are a single person or just 2 people. Its great for a weekend. But the water tanks are smaller and for fulltiming, a big family with pets, or extended vacations I would say not this one.
