Give this one time. The fueling thing has already come up.

Have been Rving in motorhomes almost 34 years and have always used the furnace when needed, this goes back to the ones from the late 70's with a pilot light, not a modern ignition board.

What was the post on traveling with propane on.With some MH that is how fridge/freezer runs.Have used the furnace while traveling in 3 different MH's and never saw manual instructions that said not to do.

Guess the OP missed the recent thread on traveling with propane on. That was a GREAT discussion.

I often wondered how MH owners keep such a large space heated from the dash only.

I have NEVER seen a statement in any Furnace Manual to NOT operate furnace while in motion.

There are warnings about blocking/obstructing air flows.......out and/or in.

'WILDTOAD'
Which Suburban Furnace Model/Manual and what was actual statement??



If floor registers are blocked due to slideouts etc then furnace may overheat due to lack of proper discharge air flow thru heat exchanger.
If return air is blocked then furnace may overheat due to lack of adequate air back into heat exchanger.
Overheating will cause furnace to trip on 'high temp limit' switch.
Then it will cool down..refire.....over heat....trip repeat cause t-stat set point has not been satisfied.

But if nothing is blocking/obstructing air flow......run it.
We do when traveling in cold temps and our rig is a 5vr. Still nice to walk into a warm unit when setting up in cold weather.

Absolutely correct. ALL sources of ignition should be off:

Absorption refrigerator OFF
Furnace OFF
Water heater OFF

Note: Just having propane turned off at the tank is NOT sufficient.

All those devises have spark ignitors that can trigger whether the propane is on or not. Spark ignitors plus gasoline fumes.....

Just make sure all is shut down while fueling.

Lawyer speak: no.

Reality: Risk is extremely low and well within risk tolerance of all but ambulance chasers.

For the nay sayers, what are the issues (assuming basic maintenance is done)?

That's a personal choice; one I wouldn't do.
