Shower drain clog.

Not sure that's really your problem.
Our last two trailers were bought new but because they use those tiny little drains in the shower, they just can't seem to keep up all the time. Why the industry keeps using drains from mobile homes built in the 60's is a mystery to me.
The problem is even worse with super soft water.

Try this, you can also get locally, WalMart, Lowes, Home Depot, etc.

I would imagine that it is a super short run to the tank from the shower. Snaking it would be pretty easy. Have you had the trailer for a while and is the problem new? If so, have you also considered checking the vent? Some times they get debris or nests in them.

Another thing to check besides a clog, is the vent pipe for the tank where it comes through the roof. Check to make sure wasps of dirt daubers have not been building a nest at the top of the vent pipe plugging it.

Did u unscrew the cover plate and look in sometimes u can get lucky see it with flashlight nd pull it out with needle nose pliers

The water in our shower drains slowly. By the time our shower is over we are standing in water. We think it must be a hair clog just because we don't what else would cause it. Our question is what should we do to fix it.

Take the shower drain coverout on the shower floor. Pour 1 cup of baking soda into the drain then slowly pour 1 cup of white vinegar. It will immediately start to bubble up. Then run hot water until it drains really easily. If needed repeat the process until your shower drains normally.

Take the shower drain cover out on the shower floor.

You beat me to it, I say we should find out if it is just a big glob of hair and soap scum in the drain. Is what happens to mine. Lets not take the camper apart if we don't have to. :W

If the roof vent was plugged with debris, all would drain slow, even the grey tank outlet.

My shower has a remove able goose neck, in basement right under the shower pan.

Seems IIRC, someone posted a while back, that wife with long hair, best to use outside shower???

Some RV's don't use a p-trap for the shower drain. i can't remember the name but I call it a duck bill drain. Look for an access panel to get under the shower.These thing go bad often.

I made a tool to clean my drains by wrapping a bicycle tire tube around the male end of a short piece of hose. I connect the female end to my garden hose. The tire tube end fits into the drain and seals the ID to form a tight fit. I hold it in place and someone turns on the hose, this will blast the clog and soap scum buildup out of the drain.
