Can you get to the Trap? Is shower draining OK?

Vaughan, I would start under the sink and look for the Hepvo Valve, most likely just built up of crud, pull it out and clean it.
I've done it several times to ours, once it even turned it's self inside out, don't know what caused it be it did.

I have a 2013 Blackwood 36' and took out the P trap and cleaned it, had a bunch of goop in it.

Start by pouring a pot of boiling water down the drain.
Next, pour a cup of baking soda and 1 cup water/1 cup vinegar solution.
Cover with the drain plug and wait 5 to 10 minutes.
Pour boiling water down the drain again.
