2012 357QS.......We are just starting to use our furnace and last night it was cold, 30 degrees and windy, it's just me and my wife and we are dry camping, last night I decided to be safe so I ran the generator all night. I set both thermostats at 72 we stayed warm but my questions are. Do I need the front and rear on to keep the motor home warm or should I just try the rear, would my house batteries run them both or just the rear all night without discharging, do I have a furnace filter to change like a home furnace?
Your furnace runs off propane I am sure you know....the batteries supply a small amount of power to the control board of the furnace which all things being perfect, your batteries would run just the furnace for weeks....so over night you will have no problems with your batteries.....if you are dry camping then perhaps you should run your genny a few hours a day or much less or not at all if you have a solar panel. Which furnace you run depends on your own comfort....we have two AC's and can usually get away with one unless it's boiling outside and finally, I don't believe you have a furnace filter that needs cleaning or changing.
Furnace runs off propane but each furnace motor draws app. 6 to 12 amps each (depends on size of furnace), so depending on the state of your batteries, you might be good all night, maybe two without using generator, but not weeks. I guess you will find out tonight.

WDK, I think you are forgetting that the batteries also run the blower motor that turns two squirrel cage fans. One provide burner air for the propane and one that pushes air throughout the camper's vents.
Depending on model, the furnace can draw from 3 to 11.5 amps of 12 volt DC when running.
Assuming the smallest single BTU heater (12,000 BTU 3 amps) running constantly; a fully charged standard 75 AH deep cycle battery will be completely dead in 25 hours with no other draws.
Larger (or multiple) heaters will last much less. For example an SF42 furnace (42,000 BTU) drawing 11.5 amps (and running constantly) will kill a fully charged single 75 AH battery in about 6.5 hours.
Obviously, the heat should not run constantly (unless you have a window open) and motor homes typically have more than one battery, so actual "heat on" times will vary greatly depending on outside temperatures, battery capacity, and desired comfort level.

Yes your completely right about the blowers and weeks was quite the exaggeration on my part though again depending on your comfort level I have gone a couple of nights dry camping running my gen on 3 hours....my point being that if his system is in decent shape I think he can go all night without having his generator running. I have personally gone a couple of nights with temps being in the mid 30's with my thermostat set at 68 degrees. Your battery indicator lights on your utility panel will give you a good indication of where you are. On any given subject one can use all the input we can get and that is what this forum is for.
it's just me and my wife and we are dry camping, last night I decided to be safe so I ran the generator all night.
i have to ask, every campground i have ever been to or seen, does NOT allow running generators all nite.
what campground were you in, that allowed this?
unless you were boondocking, instead of dry camping. dry camping is camping in a campground without any hookups.

Dry camping and boondocking same thing to me and I'm pretty sure everybody but you knew what I meant. Do you really think I'd be running my generator if I was hooked up to electricity? If you really want to know we are at a race track with no hookups and thank you for your valuable input on my question.
I was at the the Phoenix International Speed Way a month ago at an RV rally and while they had certain sections....ie some had full hooks ups some could run their gens 24/7 and some had no hook ups water or electric which was the section we were in. You could only run your gen from 7am to 11pm and since we were at the rally much of that time (at the booths and classes) we only ran our gen a couple of hours in the morning and an hour or so before going to bed. When your in a community you follow their rules.....when your boon-docking, while you can still piss your neighbors off, if you have any but you can make your own rules and hopefully still use proper etiquette ie don't dump your black tank on the ground..... and that's the difference.

i think you misunderstood me. many state parks do not have electricity. in California, where we used to live, less than 1% of state park campsites have electricity.
that's why we're used to not having electricity, when camping.
i apologize if i offended you but that wasn't my intent.
and as to the term dry camping vs. boondocking. i've been on many RV forums for over 10 years and the generally accepted definition of dry camping, is camping at developed campgrounds that have no hookups.
camping at race tracks, deserts, national forests, etc..., where there are no developed campsites, is generally defined as boondocking.
so, that's why i asked the question. if you were at a race track, then i agree that running your generator all night is not an issue.

The furnace fan runs on 12V and will sap a regular battery pretty quick, may not on a motor home with much larger batteries.
Something that has always baffled me on here is that while all input is good from everyone with a bit of knowledge, I was under the impression when I enter the Georgetown forum that we are all taking about Georgetown's motor homes not 5th wheels or class c's or another type of pull trailer and I am often mistaken thinking that when I select this forum that we could be talking about nearly anything that rolls.

The first part of this quote refers to a regular battery or on something other than a motor home when I thought all we were referring to here was the Georgetown motor home.
I am simply saying that I visit two forums on here one is "what did you do to your camper today" where it seems everything is talked about all things camping and not....the other specific forum I go too is Georgetown specific which the 357Qs is but here people bring into the discussion questions or answers that refer to their 5th wheels, pull trailers other different brands of coaches etc so even though the label is specific to Georgetown's, not all the content is so as I speak here my info refers to the Georgetown set up.
When it comes to propane furnaces, there is little difference between a good sized 5th wheel or a MH. In both cases the blower motors have significant drain on batteries. I have owned several of both. Nobody has mentioned operating a MH gen set all night on a light load. I prefer a few hours in the evening and again in the morning which has been adequate. And running a gen set late at night is rude under most circumstances when there are other campers nearby and that's why most campgrounds prohibit it. There are exceptions I know but I wouldn't want to stay there. And I can't imagine trying to sleep with my own gen set running. I don't like to run my bedroom roof air at night either.

As mentioned, a motorhome furnace is for the most part the same as every other RV furnace. When a question is asked in a specific forum about a general use appliance, the assumption, by those trying to help, is that the poster would like "the answer" as soon as possible.
If you wanted an answer from only a Georgetown expert, you could get "crickets" for quite a while till one with the requisite knowledge logged on, and took an interest in answering a question that should have been in the correct appliance forum, and MAYBE gave you useful information.
Then again, maybe not.

I get that though perhaps what I am saying is unless your surfing all makes and models how do you even know the question about a Georgetown is even being posted. I don't see questions about the Berkshire ask under this label or questions about other 5th wheels being ask...I don't have a problem with anyone trying to answer a question but I don't recall seeing a question asked here about a model other than the GT. I got too many other things going on and trying to keep up with my Georgetown is all I can do but if you got the time I am all for answers from anywhere they might come.

To the right is a list of recent posts from all forums. If you choose the new posts tab at the top it shows all new posts from all forums as well. Both of these are in order of the most recent posts. Neither are sorted by individual forum. As stated before, there are some questions that are motor home and even Georgetown specific and some questions that can be answered by owners of any type of rv be it a tt, 5er or MH. We do also get some new members who post in wrong areas, as mods we try to move these items.
Speaking of inappropriate, this thread has been hijacked, let's get back to the topic asked by the OP.
Hello, Just looked up the specs for a 35,000 btu furnace. It draws 7 amps. I have read the manual for your MH and it does not say what size batteries you have. If you have Group 24 Battery i estimate you would be able to run overnight on Battery running 50% duty cycle for 7 - 8 hours. Having your battery (s) size would assist in providing relevant run times.
