I have the Moeller 22 Gal tank on my 1984 Montauk 17. It's mounted under the RPS and was held down with those nylon straps but it's still moved around a little so I used the stainless hold-down brackets. My tank sits on the two original rubber mats with the edge lip removed where they meet giving a large flat area for the tank so sit on. I don't think you really need anything under it if you use the brackets to hold it still. Anything not a solid surface, like strips of teak or plastic or rubber is just going to be putting hard spots on the bottom of the tank rather than even flat level support. By the way, that same tank, same dimensions and all, used to be rated at 24 gal but I think because the fill is aft in the boat that side of the tank is lower so you can only get 22 gal in there. In any case. love mine.
