I own a 2008 Heartland Razor fifth-wheel. It has a corner shower with surround. The faucet assembly is leaking and my RV tech seemed confused as to how to access and remove the faucet to replace or repair it. I read a similar thread dated 4-28-14 where a member had a similar issue. One member cut a access panel and made a plastic cover piece. Is this my only option here or are we missing something I will go take a photo and upload tonight. thx.
