Using Furnace While Driving

We run our furnaces on the road whenever it gets cold the dash air doesn't do much by itself.
And if you have enough battery capacity run it at night if not plugged in.
We only have four house batteries and have run the furnaces off them several nights. Check your manual. All that runs off the batteries are the blower motors and thermostat, if that..plus the usual fridge fan even on propane etc.
In 2010 I think, we came back from Disney World and it was not higher than twenty degrees the whole way. we ran the furnaces and like to have roasted as the switch to the rear furnace the contacts stuck, so we seated then froze then sweated and froze. e also had a big hole under the shower ptu there by the dealer. Factory repaired it and both furnaces running it is nice at any temp outside and the water tank get heat too.

My AC blower motor bearings failed a few years ago and I attributed it to running the AC while driving.

Probably more attributable to cheap bearings.

If the bouncing damages the fan bearings they were bad to begin with.. The only "Danger" is flame out (Wind caused by travel blows out the flame) and if that happens the very nice control board will attempt a relight.. 3 times out and it locks out and shuts down.

Your batteries don’t allow even one night using the furnace when you arrive with a hundred percent charge? If so you are not “self contained.”

Again, motorhomes drive with their roof A/C's going. I've been know to fire up the genny and a/c's before we get to the campsite when it's hot out.

Another reason I like my motorhomes, no need to run the furnace while in motion.

Done it many times myself, usually set T-stat at about 55, but in your case 70 would work. I would do it for the entire trip, made finishing heating much easier.

Shouldn't be a problem. Motorhome owners run gas furnaces frequently while on the road and I don't believe there is any difference in furnaces used in motorhomes vs. trailers.
