How much is too much? Electrical question.

Use the propane furnace and the stove top
We have switched back to a stainless steel stove top percolator many years ago

If you expect 120vac power without running the generator you will need an inverter.
If you have an inverter it will operate fine up to its rating and until the battery is dead.

What you need is a voltmeter to better track the charge level on your battery.

These questions indicate strongly that you need to do some basic RV electric reading. They are fundamental, basic etc. Then ask here. Boondocking is out in the boonies. Dry camping is without any hookups. Parking lots are for a quick snooze.

What the old man meant to say was, you posted this in the wrong forum:S, you should ask the Mod move it to the Tech Issues or General RVing Issues.

There is a short description for each forum subject when you click on it. The subject you clicked on is for help posting, not help learning.

No big thing just a cheerful note.

Now to try and answer your question. Well first I'm going to ask a couple, would you let us know which Georgetown you have and how many batteries you have. I assume you have two house and one chassis but then again I could be wrong.

But as Bud said, a lot of us use percolators and our propane furnace. I use My Cup of Joe and K cups but heat the water with the stove. Your TV will draw less than nothing, unless you have a 120 Volt AC TV but even then it's not a big draw. If you have a 120 VAC TV, I'll bet you already have an inverter. You should be fine for up to maybe 3 days on two golf batteries.

The more you tell us the better our answers can and will be.

So welcome and post questions with background info and you'll learn a lot.

Hello everyone. Thanks so much for answering my questions. Much appreciated.??

Please let us know;

1. If you gave an inverter
2. If you do, how big is it?
3. How many coach batteries do you have?

With that info we can give you a much better answer.

... and whether 6 or 12v batteries.

With a single 12v/225-235AH or 2-6v/225-235AH, you can last 1 night running the furnace. You might get a little more out of it but you will still need to run the engine or gennie to recharge your batts. Furnace fan chews up quite a bit of energy.

I have a 2019 Forest River Georgetown. I’d like to have a cup of tea in the morning, and watch TV in the evening. How about plugging in a small heater during the night. Can I do that without adding anything new to my Motorhome? I don’t have solar panels, or extra batteries, so what can and can’t I use while boondocking in a parking lot over night, without putting on the generator?
Thank you.

Your only viable option is using the installed propane heater. Anything else will require additional hardware (inverter, batteries, portable propane heater, kerosene heater,,,). Maybe a 12VDC car blanket.
