blew a inside tire on Maine turnpike. took out the screw out cover that you put the sewer hose thru when dumping the holding tanks. need to replace the whole thing cover that screws and the part that it screws into on the bottom of the cabinet floor. don't know what its called or where to find one.
Welcome to the forum!
That Amzon part looks like the right thing. If you go through Thor, you'll have to have a dealer order them for you. You can call Thor and get the part numbers. Good luck and report back!
Bad decisions make great stories!
