Goldcountry:
Welcome to IRV2
. As John suggested, call HWH. Every HWH hose has a number printed on the hose every 16" or so...you can give them that number and they will tell you if that particular hose is one they've had problems with. If so, they may send one no charge.
If you are mechanically inclined and can remove the hose yourself, you can get a new hose made up at most good auto parts stores...NAPA, etc. I did that for my rig and the hose made locally was, frankly, far superior to the original hose.
Good luck with a solution and please come back here often and share your RV experiences with us.
