Want to add a shutoff valve to the supply line but doesn’t appear there’s enough water line? See pic
Suggestions please

Yup……not much to work with. Installing a shut off is a good idea, but I have to ask……is your set up leaking? If not, you may want to leave well enough alone.

If it’s not leaking, join the thousands of the rest of us who don’t have individual shut offs either. If you’ve got the time (when you’re back home) it looks like you’ll have to figure out how to gain access to the wooden channel access where the hose enters. Take your time.

You’ll probably have to add hose length to have more hose before the toilet to install an in line tap. It actually may have to exit the wooden channel further away, to give you space. Just cap the existing opening behind the plastic cap you see today.

Thanks.
I see spoke with dometic support and I know that the supply line is 1/2” but they could not tell me the size of the male screw on connection to the flush valve. If I knew that size, I could possibly find a shut off valve to replace the female end.
No, it’s not leaking but I’m trying to modify as a preventive measure.

Here is one I put on a Fleetwood I used to own. The toilet was on the passenger side and would stop up from time to time. I wanted a way to shut off the water while I plunged it down and across to the tank. I will never buy another motorhome with the toilet on the passenger side.

I would delicately take the top luan of the box in back to see what type of octopus mess is behind there. Maybe fit your valve back there hidden and make the cover of box easily removable maybe Velcro then valve would be hidden. That would be my thought. You may have 2 frog hose curled up behind that box.

OP, do you have basement access under your toilet?
If so, put the shutoff down there.

In my previous trailer I had a 310 and just cut the supply line and installed a sharkbite stainless steel braided hose with a shutoff valve from Hoke Depot. You want one with a 1/2” faucet connector.
