My city water flex hose sprung a leak in my 2014 ACE. Has anyone replaced this hose? Is there a better hose than the OEM one? Was it hard to snake the new hose through the under floor area from the inside connection to the outside connection? Fortunately, the leak was in the "basement" compartment that houses the water heater and furnace and not in the coach itself. The furnace is fine. I have tested it to make sure.
