Another question about the '77 Holiday Rambler I acquired.

Looks like the thermostat is missing....I do have paperwork on it and it WAS a Cam Stat T17H or TM17H (not sure which...the manual has both printed on it) so are there special RV thermostats or can I just pick one up at the hardware store?

While I'm at it - and a related question - I found the furnace and it looks like it has new duct work. There is one hose that goes from the furnace to the heater vent and I saw another hose that comes out the other side of the furnace and it just runs underneath the dinette benches and just ends there. I'm sure this isn't correct...any thoughts on that would be great.

The thermostat is for what?
The vent under the dinette bench should probably come through bence base to a louvered vent plate.

Sorry wizard... The thermostat for the heat/furnace. The one that's usually on the wall that you turn up to turn the heat on. Guess I didn't make that very clear... Oops.

And to clear up the hose question.... There are two hoses coming from the furnace. One does come to a louvered plate... There is another hose that starts from the other side of the furnace and just ends underneath another dinette bench. Maybe it's supposed to run to the bathroom? If I don't end up using that one I would guess I should plug it up or something.... Just having hot air blow inside a bench compartment doesn't seem like a good thing.???

It's a good thing if you need to keep the water pipes and tanks from freezing during winter travel. The basement should be heated.

Most furnaces have knock outs that you can add a foil hose or two.
Check the air intake near furnace so no blockage, the more air it can draw the more heat you will have.
No sense on being cold this winter.

So that's a usual thing Stan? Having a hose just lay in there? Makes sense now that you mention it. I did notice that those benches seem like new construction so perhaps he had that second hose running to a heater vent at one time... I'm not sure.

I don't know much about how RVs were constructed in 1977, but I assume they were somewhat less sophisticated than today's rigs. It is standard costruction to have heating ducts leading from dash heater and furnace to the basement to keep plumbing and tanks from freezing in during cold weather travel and camping.

It is not unusual for us to travel in temperatures as low as 0 F.
Some of our Provincial parks here in Ontario are open all winter; and have camped in major snow storms in sub freezing temperatures without our plumbing system being compromised. We normally use electric heaters to heat the coach during cold weather until the temperature gets below freezing; then we use the furnace to make sure the basement is kept heated.
