I hope I've named this topic right....I'm very confused about something. First of all I do not yet have a generator and it's not in the budget for some time.
I'd like to be able to plug in a few low end items in the trailer but none of the plugs run off the batteries.
I'd also like to run the furnace w/o electric but it doesn't kick in unless plugged in.
Is there any way I can get some plugs to work for smaller items and get the furnace to run w/o electric or a generator? Help!

You didn't describe you interior's accommodations, so I'm assuming you have a fully equipped LQ if you have a furnace. Your trailer should have one and possibly two batteries. With their switch "ON", you should have DC power to your lighting and various gas/electric appliances. Your furnace, hot water heater and refrigerator should run, using only your battery power as an ignition source. Heavier usage items such as strip heaters, micro wave ovens and air conditioners can only run on shore power cords, because of their high energy requirements.
Usually built into your electrical system will be a converter, which turns a/c power into d/c power and it is also used to charge your trailer's battery (ies). This is designed to furnish your trailer with both a/c and d/c power while not depleting the batteries.
Your trailer would have to be equipped with an inverter, to run any a/c appliance off of a battery. It's voltage life span ( ampere hours) would be used up very quickly, and it would not be able to generate enough amps to run any significant a/c loadings.

I have 2 batteries. I tried running the furnace earlier and it didn't seem to kick in with just the batteries. I can't remember if I tried when I had only 1 or not. I'll try it again.
I have a fully equiped LQ but with a cowboy shower. i know I can't get the heat strip to work w/o elec or a generator nor the A/C but I was hoping the furnace would work with just the batteries.
I still need to figure out how to get some live plugs with just battery so i can run my laptop or small TV.

If you have two 6 volt batteries, both will have to be charged for your electrical system to work properly. If you have 12v batteries one will work, but will not last as long.
When you are trying your furnace, do you have your battery switch "ON"? Do you have a built in volt meter that shows the status of the battery's condition? Are you sure the furnace isn't igniting because of the igniter, or could in be caused by air in the propane line? Is your gas tank valve on? Sorry lots of questions, but there can be several reasons why your furnace isn't working.

I run a tv and dvd with an inverter with no problems. I just got a cheapo harbor freight inverter a couple years ago to see if it would work and how much I would use it, I think it's 400W with 800W surge, price was around $20. It has saved me lots of generator hours, at least 100 hours of run time in the last year so it has paid for itself several times over. When it dies or when I get a bigger tv I'm planning to get one of the higher end ones and mounting it in the lq itself, the one I have now I just hook to the batteries and run a cord in through a window.
Your furnace should work on batteries ok if they are charged (and the battery switch is on), it's working off dc power when the trailer is plugged in so there should be no difference. First thing is to make sure the furnace is working when plugged in, if it does go from there, there are many people here that will help troubleshoot.

thanks everyone...i'm going to give it a try as I'd like to primative camp yet this year w/o freezing the buns off.
On the inverter - I'll have to check into that. I'd like something more 'Fixed' but willing to try whatever. I'm not super handy but am persistent and not afraid to ask questions!!!

One thing you could do is have a catalytic propane heater installed, it uses only propane, no battery or electric needed, and no vent has to be installed.

Make sure you have a CO detector that hasn't expired. Most do after 5 years.

Yep, that's it. I think I got mine when it was on sale or I had a coupon. There are much better ones out there but they cost way more than that does and it works fine for small stuff.
