I did the same as Illapah, but then a nice MOC'er sent me a holder. The OEM in the Montana is plastic and flimsy, but it will hold the shower head bouncing down the road. Oxygenics makes a holder specifically for their shower head. I had a difficult time trying to find one that would fit, and then the nice MOC'er came to the rescue. Sent it to me from Alaska. (I think)
Edited for poor spelling.
p.s., Even with the original shower head and holder we lay the shower head on the floor of the shower. Probably everyone does that. No brainer.
