Nothing in the trailer is quite square or flat, so the pieces of wood that covered the wheel well compartments teetered up and down a bit. The couch pulls out over these hatches when you turn it into a bed. The worst part about it all was when you got out of bed. The hatch tipped and made a LOUD smacking sound. Not, thankfully, when you were in bed, but when you got out. Very annoying. I bought a 2" wide roll of Velcro and ran around the trailer putting pieces of the fuzzy half in strategic places. There were other spots where wood pieces were rubbing against each other. I used the Velcro there too. A little piece will do it.
