I thought if you were plugged in the converter would run the twelve volt even if you didn't have a battery? Does the furnace fan use too much juice for the converter to keep up? Or am I way off base.

Just FYI. If you ever come back and your AC or HP has shut off by itself, when pkugged into 120v, the E7 error code on the thermostat means there has been a 120v power interruption.

Plug in and crank up the TV for a while as a temp generator

While boondocking in Chaco Canyon at 20 degrees we ran the battery too low to power the heater fan, so I plugged in and idled the tow vehicle for an hour or so to power the heater fan to heat the trailer up enough to get back to bed for the rest of the night and keep the trailer from freezing. Had set the furnace temp at 45, still too much heater fan for the batteries. One Renogy 100w panel wasn't enough to recharge the batteries fully without a full day of good sun, so we left at noon as the haze came in as temp was projected at 19 the next night.

I'm an older female of relatively low BMI who gets cold easily, so I combine a good quality sleeping bag with the Rumpl Down Puffy, which is the best option I've found as far as down comforters go for a trailer or van. This combination allows me to stay warm while engaging in bare minimal use of our furnace to conserve battery and propane. I've camped in the 30's and had no complaints, but the Rumpl was the key to comfort for me.

We carry down sleeping bags for just such an eventuality. They keep us plenty warm and allow me to set the furnace low, around 40, to keep the water from freezing. I then turn the thermostat up to warm us up during breakfast & bathing. The bags weigh little and are very compressible, if space is at a premium.

Timely post here. We are leaving for CO soon. I have always ran the little propane furnace in our campers. I've also never had the little furnace be that big of a drain on the batteries, I guess we've been lucky. Thinking back, our coldest nights to date with the 23FB, we've had an Elec hook up. Not so on this trip, and my batteries are getting old. They still test ok, but not like new. I'll have to watch this pretty closely.
FYI, we do not like the heat pump, it seems too loud.

So as reply, learnings and results...

1. as the reply above stated I found the furnace option on zone 1 and it blew wonderful heat into the trailer. I like how it heated the floors up as my feet were the coldest.

2. If you use the furnace be aware of where the vents are, my guitar sits right by master bedroom vents in my 30fb. So, make sure the vents are cleared.

3. As on commenter said, the vent outside blows some really hot air out, which is great if your hands are cold. But my truck was parked on that side, so I made sure it was far enough away that it wasn't cooking my paint.

4. Yeah, and if you have never used your furnace before it may set off the smoke alarm. I took the battery out of the smoke alarm for the first hour running it and once I replaced it I had no more alarms.

5. We are completely boondocking at a beautiful state park and I haven't connected to the truck or a generator for 1 day and a half. Many people commented the furnace will take out the battery in as little as an hour to overnight, however we used the furnace for 4 hours yesterday morning with outside temps at 45 degrees and putting inside temp to 68. Additionally we started it up again around 8:30 and ran it til 10:30 at 67 degrees then overnight 10:30 til now 6:30 am at 65 degrees (out side temps were in the low 50's.) this morning the furnace is still working great. We have used very little lights due to some solar candles we have that we wanted to try out. So, the truth is you can run your furnace all night if you have plenty of propane.

6. Regarding the battery. When I disconnected from the truck on Friday night at 9pm it read 12.3 volts (I think that is the right measurement) today this morning it read 9.8.

We've taken 4 quick showers among our group, and probably had some lights on for between 2-3 hours during our stay. I charged 2 camera batteries as well.

So, if you keep other battery consumption to a minimum you should have no problem running the furnace all night if you don't crank it to 80 degrees and your outside weather isn't much south of 45 degrees.

Thanks for all the help everyone. If you'd like to see more of our adventures you,ll find us at

I use my catalytic heater to warm the trailer but not while sleeping. I can set the front fan to blow in on slow speed and let the air escape through the vent at the back. That easily covers the needed ventilation and the fan doesn't use as much power as the furnace; quieter too

Streaminfree, for lead acid batteries, 12.3 V is about 30% discharged and 9.8 V is fully discharged. You don't want to discharge below 50% if you want the batteries to last a decent # of cycles.

Do an Internet search on "12V battery state of charge, voltage" and you should get some SOC tables.

12.3VDC is close to 30% depth of discharge for some liquid cell batteries (50% is actually 12.2VDC for AGM batteries and 12.06VDC for many liquid cells) and 9.8VDC is effectively DEAD for a lead-based battery!! (these values heavily depend on the battery chemistry and manufacturer and you should always confirm these levels with the OEM of the batteries that you are using)

If you want your batteries to last more than a season or two, you should avoid drawing your batteries below 50% on a regular basis. Keep drawing them below 11.5VDC and they won't serve you very long.

Battery experts. What's the best way to run a generator to recharge the batteries? I replaced my inverter with a much better unit that was recommended here.
So should I hook up my generator directly to the batteries, or just plug the trailer Elec hookup to the generator?
I am going to replace my standard deep cell batteries this week, and head to Colo for 8 days boon dock style camping in Colo next week. No hookups, and 40s at night. Going to be running the propane furnace.
Thanks
Jeff

Echoing recent comments on damage to batteries with reading of 9.8 volts.

An expensive way to heat the trailer maybe . . .

Jeff, no expert here, but I believe that it is best to plug the trailer into the generator, in order to keep your new "converter/charger" (I assume you meant -- not "inverter") in the loop, so as to regulate the charging rates of your new batteries. You will have the added benefit of using 120-volt appliances, television, etc. at the same time. You can also turn the fridge to electric, and the water heater as well (if your generator is large enough for this last load).

Good luck on the trip!

Peter

Thanks Peter. Yes, I misspoke regarding the converter. We were cooking batteries with the old converter/charger. The new one is much more quiet also.
Thanks again. I've been running the little Honda generator, and plugging the main trailer power into the generator. The only problem arises when my wife runs her blow dryer. Seems to draw more than the little Honda wants to produce.

You might consider a smaller blow dryer. I believe they exist, and only use the Low setting. Also, if a hair dryer challenges your gen, then the water heater will not work on electric, to modify my earlier comment, but the fridge might. We got a small Yamaha 1,000 tri-fuel gen recently, and it handles our OEM battery charger and the fridge at the same time, as long as the batteries are not very discharged. Further generator discussions should probably move over to another thread, if you want, as there are plenty of them.
