The GMC that I'm working on. 73 Canyonland. Never had heater hoses going to the electric water heater from the engine. So these hoses must have been an option on the GMC's that GM did the interiors. I've never found a Royale that didn't have these hoses. Bob Dunahugh
I though all GMC's had the engine provide heat for the water heater while on the road.

Bob,
This was fitted to all of the early GMCs as far as I could tell from the documentation. I do also know that many removed the hoses. The only thing
left in our coach was the holes in the flooring and the empty clamps. For a 23', it took most of a 50' box of hose and I had to buy the spring things
to put over the hoses to make the turn into the heater.

Both my Avion's had the engine heating the hot water feature. Hot water was dangerously hot when you hit the campground. Also, those long not
protected hoses failed and cost me a brand new rebuilt engine. There is no indication, other than water mist, that these hoses had failed. The failure
was in the run along the frame well behind the vision of either the driver or the passenger.
Lesson learned, if you have the pre-heat hoses, put cut-off valves on both hose lines. You would only have to open the valves with the engine idling
along, to get the hot water heater up to speed. A neat idea, however.....

Tom,
How about a couple of 12v solenoid valves close to the engine? When you get
close to your destination, hit the switch and have hot
water when you arrive. This would eliminate the ill effect of that
blistering hot water on those hoses constantly.

This 73 never had the hoses.
Valves/solenoid valve could be installed. These hoses are made to take these temps. I simply replaced all of mine with good quality hoses. And get a Digi Panel. You'll never lose an engine with a Digi Panel because of it's alarm. Yes. Owners say that they watch their gauges. You can lose an engine in 30 seconds with an oil issue. 120 seconds over coolant issues..

Think you could make something like this work:
https://www.amazon.com/Water-Heater-Control-Solenoid-1147412159/dp/B01EWQ5WOG/ref=sr_1_20?s=automotive&ie=UTF8&qid=1537129460&sr=1-20&keywords=electric+heater+valve
Looks like its a bypass until engaged. You could control it thermostatically..
I wonder if copper tubing using padded Adel aircaft style clamps would be better for durability? And possibly shed some excess heat?
Also, I think you could run a large heater core for either rear cabin heat, or as an auxillary cooler on really hot days.
In any case manual shut off valves accessable from the engine hatch would probably be a good idea.
