Have a small fifth wheel, very little insulation, heading to FL in February from MA. I know some folks shut off the gas while traveling, I'm not of tha camp and have no problem running the fridge on gas while I travel. Any reasons I can't run the furnace? Do folks do such? I have read where motorhomes are designed to be able to run with the furnace on, does that hold true of fifth wheels and trailers too?

Probably could run it......I know in my 5ver.......if it is really cold when I get to a new spot....it takes less than 5 minutes to heat the trailer after stopping.

doable .. Sure.... Why.. 55 mph will pull lots of heat out ...I know my 10 year old trailer.. will heat up 20 degrees in 10 minutes..park trailer.. turn on furnace.. level and block trailer... inside will be warm.

Be prepared to have your propane tanks be empty in record time. You will be sucking out the heat traveling down the road.

I don't understand the "sucking the heat out", have you tried it?Thought it would take an hour to heat it up, will try it on a cold day at home.Thanks

Just do a quick stop and start it up a half hour before you get there.

I just did this accidentally and it was kind of glorious to arrive to a warm camper. :)

I plan on running mine when traveling in the cold... I was reminded here to check registers when the slide is in. I think I have two that are covered so will need to think on that some...

When sitting still at 15 degrees the temperature in windless conditions is 15 degrees. Traveling at 60 mph, the windchill is like -11 degree. Therefore your furnace will need to work as if the outside temp is -11 degrees when traveling.

Wind chill does not affect inanimate objects. Only living creatures 'feel' the affect of wind chill.

The effect of wind chill is to increase the rate of heat loss and reduce any warmer objects to the ambient temperature more quickly. It cannot, however, reduce the temperature of these objects below the ambient temperature, no matter how great the wind velocity.

Wind chill doesn't affect an inanimate object like it does a human, but a warm object of any kind exposed to a strong airflow will absolutely cool off much faster than it would in still air.

There is also the issue of heat loss due to air being forced in and out of the RV by the highway speed wind it's exposed to.

Turn it on at the last fuel stop or the last 30 minutes before arrival.
Works fine. I do this when visiting the snow. Propane use is not an issue.

Thanks for the enlightening post.

In still air, a structure has an envelope of slightly warmer air around the outside. Driving down the road will prevent that envelope from forming and the moving air will literally suck the heat out much worse than if parked.

I guess the wind don't blow in Ohio 'eh?

Interesting subject, we just cam home from the coast thought about it in the way out as temps were in the low 30's, but chose not to.

When we came home, DW forgot to turn off the heat. :)The trailer was nice and warm inside, don't know how much it ran, but may run it on the trip out next time with T-Stat set at about 55, not 65. :B
