Our 2012 Grey Wolf is the same way. We don't use the shower much, maybe 2-3 times a year the tub/shower is actually used as a shower. Usually just the tub is used to give our DD a bath, DW and I usually just use the showers at the CG to save the water in the tank and grey water tank space since most places we camp don't have water or sewer hookups.
