What do you do to keep gray water from coming up into the bathtub when you have to drive to the next dump station?I tried buying a tapered rubber plug, but it's designed to keep water from going down the drain, not water coming up. With the shape of the taper, it just gets pushed up and out of the drain.Have any of you come up with a good solution to keep water from coming up into the tub when you're driving on a curvy road?

^^^ what they said ! ( IF POSSIBLE ) possibly use a blue tote to drop the level a bit

Yes dump more frequently. But if you can not dump you can try a plug from a swimming pool supply.Amazon

Buy a tote: or better yet two.

Bring along another container like a tote or just a 5 gallon jug to put the extra grey in. I use the jug method to extend my stay and just dump it down the closest toilet.

If you have a single discharge point. You can put a twist on valve on the discharge. Close the discharge and open both grey and black tanks. Allow grey water flow into black tank. This trick will give you access to the additional capacity left in the black tank.

Does facility allow for grey water to released onto ground? Most do not but you never know for sure without asking.

Don't. Unless it is coming out of the tub, I don't see the problem.
