I've read multiple complaints now about degraded hoses. Some leaked from day one and some will last years. Many times it ends up being the orange hoses not the black jacketed ones. Forest River/ Lippert bought the cheapest import hose in bulk and delaminates from the inside out due to the pressure. I've seen some hoses that had bubbles the entire length and had to be changed.
I'd get an estimate from a hydraulic shop in your area. They will use industrial grade materials that will outlast any original.
