Need help

I have a keystone cougar 29bhs
The tub will not drain I've used vinager and baking soda, draino the service guy at gander it wouldn't hurt the pipes . Tried plunging it as well but nothing works. The sink had holding water too but I took the air admittance valve off the pipe and that drained. Is there an air admittance valve for the shower and if so there is that located? can anyone help me?

Ditto!
The hidden second grey valve rears it's ugly head!

Look to the rear of the axles on the driver's side.

Keystone site lists capacity as 30 gal black waste, 60 gal gray waste. My guess is you have two 30 gal gray tanks.

Look on the "road side" outer wall of your trailer, just above the molding for the J-wrap. You should find a "very small, inconspicuous" decal that says, "Gray Tank" or "Black Tank". They are about 1/2" x 2" in size, white with small black lettering and they "blend very well" (hard to see)....

Check the side of your trailer for a "hint of where the valve might be" if you can find the decal.

If they have been removed or if they aren't present, crawl under your trailer, look at the frame rail (between the J-wrap and the frame) for a rod or a handle that might be there. Sometimes a handle can vibrate off the rod or the rod can vibrate off the valve and all that's left is a "small hole where things used to be"... So look carefully.

If not there, look at the underbelly covering. You may find a slit, often sealed with black foam (used around the rod to seal the space). Again, sometimes the handle and/or the rod may have vibrated off the valve body, so look for evidence of "what might have been there"....

Here's a photo of those decals, hopefully they're on your trailer.

Sometimes it's behind the pipe, get down low and take a look.

Grey tank for the shower should share the same outlet at the rear of the trailer but have their own valves.

The second grey tank is just forward of the slide and the kitchen sink is all that drains to it.

My nephew came over and found it for me. The second tank valve is right beside the black water dump pipe. The decals for the grey water are one on top of the other but the valve is right next to the black water tank. Thanks for all of your help on this matter. I appreciate being able to ask for y'all's help.
