RV Repair: shower controls on Cardinal 29WB, fifth wheel, access panel

Question
I'm trying to access the shower controls (fixture)
on the above fifth wheel. The corner shower is a
fiberglass unit and there doesnt appear to have any access panel behind it. To gain access do you
pull wall panels in the entertainment center forward of the bathroom? Or is there another method to get the fixture replaced? There appears
to be a round plastic piece held on with 6 screws
under the shower controls-would removing that
help? Any help would be appreciated.

Answer
Bill,
    If there isn't an access panel directly behind the faucet and you can't get to it through round piece you discussed you may have to remove the shower to access it.  You can reach cardinal @ 574-389-4600 and they may be able to help you further.
