Cutting the end off of a brand new expensive 3/4" hose just seems wrong.

Got the mystery box mounted and the floorboard in the bottom. Also a couple holes cut in the front.

Well here it is! It's a box for my shower sump. These things need occasional maintenance and cleaning.
I did not want to put it under the trailer and have to either slide it out somehow or cut a hole in the floor
to access it.(Too fat and old for kneeling and working below floor level.)
The hose connection on the input is for hooking up to an external hose if I want to let the shower drain in the weeds.
