More than likely you have a Hepvo drain valve for your shower drain (Click here.) These are not your home style P-traps. There is a rubber sleave inside that water passes through. It opens up and then shuts tight again once the water passes.

Two things could be going on with it. First, it was installed backwards. Second, the rubber sleave inside could have flipped backwards and reversed.

If you used a plunger on the drain, this is highly possible.

My first suggestion would be to use a plunger (if you have not already). Put some water in the bottom, put the plunger over the drain hole and push down (only once). Now slide the plunger off the hole while the plunger is still compressed. Don't pull upward on it. This will just keep the rubber sleave inside still flipped in reverse. You will only need to do this once. Absolutely do not pull upwards on the plunger. Slide it off. Thus, the reason for the water, it helps it to slide easier than on a dry bottom.

Take down your basement wall under the shower. Find and remove the HEPVO valve and clean it.

This may sound dumb but is your grey tank full?

Be very careful cleaning the Hepvo valve. The membrane is quite fragile so any snake or brush you push through there could easily tear it. Some have had luck with just simply stomping on the shower drain with water to force air through it, or flushing with a leaf blower.
If there is water backed up into the shower, removing the Hepvo valve would allow the water to drain into your basement, so bring a bucket with you if you remove the valve for cleaning.

Ya what he said. Don't use a plunger. Using your foot to force water through works for mine.

I have a 2007 3000RK
Yours will be slightly different by year
On the 2007 shower on passenger side..
there is a traditional trap
Below the shower pan in the basement
That then runs forward catches the vanity drain
Its along the top of compartment near the heater duct.
Then turns down to the tank at the forward side of the compartment.
There is a vertical pipe above the vanity that is the roof.vent

I put a cup of Dawn dish soap into the drain then used a leaf blower to force it into the drain. The leaf blower’s mouth was just wide enough to cover the drain entirely. I followed up with hot water and another blast with the leaf blower. haven’t had any problems since. Easy peasy.
