We have a 2015 Grey Wolf 23DBH that we have taken on some extended vacations over the last year.
One of the problem was when tanking a shower, the floor would be covered with water.
It turns out the water would get past the shower curtain. This cheap little thing from Wally World solved the problem, after I trimmed it on the bandsaw.
That also lead to another issue. For some reason, the manufacture didn't see fit to install a toilette paper holder. A few times over the past year my young son put the toilette paper roll in the wet sink or in the wet tub. $19.99 spent ordering a recessed paper holder from Home Depot solved the problem. (I'm a bit surprised it didn't come with a holder.)
It was very easy to install, just cut a square hold and put it in. It comes with a backing plate that squeezes the holder from the back side.
