I agree. That is not what i intended to say. The foam is just to help mitigate the downward cantilever motion as you go over bumps while underway. The correct thing is to fasten the mount so that it does not move up or down at the mounting point, while the foam support simply mitigates the downward "flex".
As for fixing the mount at the wall - I could have sworn that it was lockable, but you said you had to use cable ties so I guess it is not lockable. (Can't see the mount now as the RV is storage).
