RE: National Rv Seabreeze
Workhorse bought the motorhome chassie from GM several years ago. You should be able to locate a workhorse repair center in your area. Two other options, I had a 1988 Chevrolet MH and some of the parts for the Chevy delivery van are the same. Some auto parts houses can make hose. If you try this route take the old hose to them, they may be able to replace the hose using your fittings.
