I was able to crawl under my 16' 2001 Casita
Spirit sink only(no small feat). My drain line is broken off, there is a smashed clamp @ frame roadside. I can repair line (2" ?) but what would be the tremination fittings, a valve or cap, plug? I have no holding tank, so bucket when doondocking is no prob but what about sewer hose connection when in a park w/hookups?
