Rear Bath opening for hose

[JBP]

My XL369 rear bath opening out of the basement compartment for the black and gray water drain is too small to run the hose through.
Has anyone else having the same problem?

We had the same problem and I shaved down the taps some on the hose and it slides thru now

What did you use?

A small disc sander

The dealer replaced my 4" opening with a 5" opening. FR said that they had installed the wrong one. They paid for the fix.
