Can you use the same foam & wax seal for the RV toilet as you use in your house? It looks like it would fit but the RV seal is foam and thinner but is made to smash down.
It might work, but for the cost of them I would get the right one!

Yes for wax but I agree with Keith, but there are several thicknesses available. You need to take yours apart and estimate the amount of "squash-down" to pick the right one. In a pinch, you can form it somewhat. Too much is not good either. I am not aware of a foam or foam&wax.
