Unfortunately, Thetford Neglects to mention that the REAR of the Toilet is a Maze of Plastic. Good luck getting the Nylon nuts on under the back, with all that plastic in the way !
Why doesn't Thetford make a better toilet seat to fit the commode, and a soft close one. The bottom of the seat is a pain to clean. Why not solid plastic? Why not have washers that fit in the holes in the bowl so it does not twist on the commode?
