Lift and remove the shower drain strainer. Take a metal clothes hanger, straighten a 12" length and make a hook on one end. Now reach down the shower drain and you will find soap scum and strings of hair. Remove all debris and clean the shower drain as far as you can reach. Take a plunger and push a few times and it will bring up other debris.
STOP!!! Do not do this! There is an anti-backflow device in the drain line. Attacking it with a close hanger or other metal wire will ruin it.
You don't say which model Montana you have, but all of them, including the 2012s which I have one of, have three tanks. The black tank is all by itself for the toilet (with an occasional screw up by the old world craftsman who plumb the washer into the black tank), a galley tank for the kitchen (the one with the hard to find handle), and the shower/sink tank. It sounds like your anti-siphon (there is a technical name which I can't recall) is clogged. Remove it from underneath (take out the back wall in the pass through compartment to find it) and clean it out.
