I have a 2014 31.5 RLTS and have a leak from behind panel in compartment where water, black tank flush, shower hose, cable hook up are located. Only leaks when city fresh water is connected and is slow leak. With access panel so small I can't really tell where it is coming from. Seems it may be compression fitting on rear of fresh water connection or fitting on rear of shower hose connection (maybe crushed o ring on compression fitting?). Can't get in to tighten the nut. Anyone else have this happen?
