Went on a three night campout. First night out the on demand water pump quit working. DH changed fuses. Still no go. Had to replace this in our other HiLo. Wanted to get one over the internet. It wouldn't arrive in time for our next vacation. Will make a trip to our HiLo dealer. We have a 199626ft. Classic HiLo. The couches in the front fold out to make a queen bed. I had a custom mattress made and added a topper(comfy). Next we have to wrestle the heavy/awkward mattress off the couches. It will fit width wise across the sink and dinette bed. Then you get to crawl under the mattress to access the couch. Possibly have to unbolt the couch. Note to self put a piece of blue painters tape on the back of the couch . This greately helps for correct reinstall. Ask me how I know. DH hard wired in a surge protector under the couch on the drivers side.DH says the furnice duct lays on top of the pump. Do you have to cut the duct? How would you repair this? Worst case I take a picture and email it to my dealer. Just want to get all the parts when I am at the dealer. Has anyone done this repair? DH is very handy and diagrams wires before disassembly. Any advice appreciated. Will purchase a quiet pump. Thanks
