undercarraige roller??
While camping at a county park recently, I saw a TT that had a large roller wheel setup behind the rather low slung waste outlet, I think to keep it from bottoming out. The drain on our TT is sort of low and far back and it occurred to me that a wheel like that might be a nice extra to have installed. Has anyone done that??? I have done an internet search but without knowing the correct name for such a thing, have come up empty so far. Any suggestions will be appreciated.
