On my '14 I also found the factory setup very limiting and just recently removed it, installing a marine removable access plate in its place. But I actually added a second one too, directly in line with the tank outlet, removing the factory cable/water hose pass through, enlarging the stock hole with my Dremel to accommodate the marine access cover seen here: Amazon.com: JR Products 31035 Black 5" Access/Deck Plate: Automotive
Now my hose doesn't take a bend across the compartment to exit at the rear, it just comes straight out. I may reuse the removed hose access assembly, putting it next to the remaining one so I can have multiple entry paths for the smaller hookup accessories.
I never thought the stock setup added anything, I could not even swing it towards the rear of my coach since it would hit the bottom of the compartment doors.
