There's no way I was going to twist the tube down for dump and up for travel (wasted effort IMO). So for the last couple years I've left it down in the dump ready position. Put a dixie bowl in the round hole to help keep stuff tossed from the rear wheels out of the compartment.
Finally I got rid of the bottom ring assembly, with those screws just waiting to rip up my hands during hookup. Printed a better bowl to perform the same purpose in the bare hole. There's really no reason to have that screw in plug for a tight seal when there's so many other huge holes cut for the plumbing.
