It should be much of a issue. I think the blower motor draws about 8-10 amps. At least for my Atwood heater in my Jayco.

Your battery should be able to power the furnace for several hours. With the TV recharging while on the road, there should be no problems. I survived the ice storm of '15 in Greenwood SC along with an 18 hour power outage on just battery power. Temps were in the sub 20 range and the trailer stayed nice and toasty the whole time, no freeze ups at all.

I am surprised to find that the furnace can run on just the battery!!! Power from the tow vehicle should easily recharge the battery if needed, while towing.

Well, I bought this thing in May, and have one half-full bottle (since new). So I ran the other bottle only, and just last week had it filled, and it was still at 1/8 tank or so. But I wanted to get to that "1 full, 1 half-full" condition, so I had it filled before it was empty.

And we have used it for 2 two week trips this winter, used it to cook thanksgiving and Christmas dinners, heated the trailer, and ran the fridge on gas while driving, not to mention cooking while on 3 other week long trips earlier this year.

So, as far as using too much propane...I am not all that worried.

And propane is relatively cheap.

Thanks for all the feedback. I hopefully won't have to do this, but if we end up taking a surprise trip up through the Colorado mountains and into Wyoming this winter, I wanted to be sure I could do it without having to winterize it each day, and just hit the road and keep the trailer warm during the day while we are traveling.
Yep, our last MH had a 40 gallon (32 usable tank) we only used it for cooking, heat and hot water although most of the time we were on shore power and used electric heat and the water heater had a factory electric element. Every couple years I'd top it off with less than 10 gallons or so. The present rig only has a 5.5 gal tank just for the cooktop. Not sure how long that will last as we very seldom use the cooktop.

RVs are self contained recreational vehicles meaning that fridge, water heater, furnace, water pump and stove all can be operated without AC power.

All of the above run off of RVs battery and/or propane systems

Furnace is biggest DC hog..rule of thumb is one night of operation per12V battery

RVs battery can be recharged/maintained by vehicles alt. and charge line.

Turn your furnace ON and travel

Only issue would be IF too many registers are blocked, return air flow is blocked with RV in travel mode.
Furnace would trip......safely shut down .........should lack of proper air flow exist.

Please explain "travel mode" and why air flow would be restricted...

Small trailer, only has two registers. One in middle of floor, and one coming out below the shower. Return flow goes (I think) to under the kitchen sink.

I hope it works, because we WILL be doing winter travel in the near future.

Travel mode is when you stuff all the outside gear in the trailer blocking the air registers.

That along with slides covering them will overheat the furnace.

Like my Jayco has 4 register two a partial covered by the slide. I've fired up the heater several times with the slide in and never had a issue yet. Typically I'm not traveling till temps are above freezing. Most of my water lines are outside the living quarters so running the heater is mute point and won't solve my issue. So this brings up a valid point do you know where all your plumbing is located?

Well, then I don't have a travel mode. My registers are in the bathroom and right in the middle of my floor, both are un-obstructed when everything is pulled in for "travel mode"

Exclamation

Keep in mind that while traveling you have a strong wind blowing over the trailer reducing the air boundary layer next the trailer's skin to almost zero. This will require some additional heat input and thus propane.

I would strongly encourage anyone thinking about driving with propane on study up on those dangers. You maybe able to get away with doing it if all goes well. If you have a collision and a propane line is damaged it becomes a very different game quickly. I once watched a Class B being driven explode and burn from a propane problem. The crew bailed and ran for their lives just making it in time. Also possible while at a gas station if your heater comes on and there's a strong concentration of gas fumes you may have real fireworks show. Instead you might consider running up your furnace while at rest stops and lunch time and then shut it down before starting out again. This would add at least some extra heat while in route. Just saying caution goes a long way in this business.

So, I should be towing with the gas tanks off? If so, will the refrigerator continue running off the tow vehicle's electricity?

I have always left the gas on thinking that keeps the fridge running while on the road...

I love this forum...seems like I learn something new every day!

There are risks and hazards with everything we do. The risk of a propane fueled post accident fire? It's there but pretty low. You're more likely to become fused to your truck in a head on with a drunk driver or may be become a snack for a bear once camped, blow out the left front tire and end up heading towards on coming traffic and the list goes on.
