Florida bound end of December, furnace question

Newbie to posting. We are travelling to Florida from Kingston Canada at the end of December. My question is can I run my furnace in our 5th wheel while driving? We previously had a motorhome and ran the furnace while driving. Thanks in advance.

  • Just something to keep in mind when running the furnace with the slides in.....if the slides are blocking furnace vents, it can cause issues with the performance and a shut-down. If you read the manual for the furnace, it states that a minimum number of vents must never be closed or blocked. I'd suggest reading the manual for your furnace in that regard and see how many of your vents will be unobstructed with the slides in. Safe travels!
  • On a long winter road trip I turned my furnace on when I left home and off again 6 weeks later when I returned. Same for the water heater.

    Both are equipped with DSI, there's no pilot light to mess with, same as the fridge.

    If your trailer is old and still using pilot lights, well, your mileage may vary.
  • Maybe you could but I don't. I have run it for 15 min. or so at a rest stop. Doesn't take much heat to prevent freeze-up unless it's super cold.

    Not positive but from what I've seen and read here I believe this to be exactly the opposite. Most would.

    1st time by accident. Now will do in the winter all the time. Set T-Stat about 55 degrees, let it warm the cool and dampness out of the rig, dog will wam then easly mot 65.

    I don't think it will hurt anything to run the furnace on a 5er while on the road (or a TT), but don't be surprised if you go through an excessive amount on propane.

    If yours has a pilot light that needs to be lit, then it probably will not work. Once the thermostat reaches temperature, the furnace will kickoff. Wind from driving will blow out the pilot light. If yours is an electronic ignition, the flame may have difficulty igniting as wind would be blowing propane away too fast.

    All you can really do it try it and see what happens. Worst that will happen is the wind will blow out the flame, furnace will attempt to restart 3 times and then shut down.

    I for one have never towed with the furnace or water heater on. Always with the refrigerator on, but never with furnace or water heater.
