Using Furnace While Driving

[2112]

We hit the road with the FW yesterday for Easter Weekend. Our destination park will not unlock the pedestal after 8pm so I knew we would not have power until ~8:30am the following morning. The temperature was in the mid 50's with an expected low this morning of mid 40's (47 at the moment). I decided to run the furnace for the last hour of our trip to warm up the FW in order to preserve the battery once we arrived.

I was uneasy doing this, concerned the bouncing may damage the fan bearings. Did this do any harm to my furnace fan bearings? What type of bearings do the two furnace fans have?

Thanks

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

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.
