I just replaced all the heater hoses on my 02 DS. Had one break on I-10 outside of Yuma. The 2 long front to back heater hoses were trapped inside the tubular steel frame rail so they had to go on the outside beneath the floor system. You don't want to pay the price to have one replaced on the side of the Interstate like we did. I also had to replace a hydraulic fan motor and the Tech said my hydraulic hoses look OK so I won't worry about them for now. We have spent $$$$$$$ on maintenance items the past year but we decided we will use this Motorhome until I can't drive anymore.
