I added the hose master with remote for both the hose and cable reels to our 38 foot FDTS '05. As Basil mentioned, there is a reset button on the side that has popped when the hose has gotten jammed, I would check that before I cut any holes.
I have found that I was much smarter when we originally chose our coach then I realized. The '05 FDTS 38' has a couple of advantages that I was not aware of and certainly did not look for at that time. The Hydro Hot is accessible from the curb side compartment in front of the rear wheels, just remove a trim panel, a couple of screws, no cutting and you also gain access to the inverter. Now I discover that the Hose Master is in an easy access place.
