I'm not sure what battery I have on the camper but I am sure it has the original battery (I'm at work or I would go look). It's a 2017 Cruiser RV - MPG 2400BH and has a 30,000 BTU heater. We have not been brave enough to try any dry camping yet but was thinking about it tomorrow night. We are going to be traveling to Colorado for a long weekend and I was hoping to take off Thursday afternoon and drive about half way and then finishing the trip Friday morning.

My question is this, I believe it will get down to around 50 degrees Thursday night and am wondering how long I will be able to run the furnace on that original battery. Will it make it through the night if I set the thermostat st 60 - 65 degrees and don't use any lights or any other power? We will have full hookups at our campsite in CO so it will be fully recharged the following day.

I have read about the catalytic heater option with low oxygen shut off but I just can't pull the trigger on that with my wife and 3 boys in the camper. I'm sure it would be fine but I just can't do it.

Should be easy to determine the amp hour draw and then your battery’s AH capacity with 50% useable. What make and model heater? 60 to 65F overnight seems warm to me, however. Dry camping is great! True freedom.

50 is maybe not even cold enough to cycle on much. I think you will be fine with the temp set at 65 or lower.
Worst case you will have a bit of a chill in the morning.

At 50 degrees I would have the windows open and enjoy the cool air. Or just use extra blankets and take off the chill in the AM when you wake up. Just other options.

LOTS of variables. How many batts do you have, how old are they, what condition are they in, how warm are you planning on setting the t stat, what's the R value of the rv, etc, etc.

All that said, one batt, in good shape with a full charge should get you through the night at 50 degrees provided you don't set it to 80.

One note, open a bath roof vent or something. A by product of LP burning is water vapor and will drive up the humidity in your RV.

I cannot find it in the specifications, but if it is a single battery, then it is a bad bet. With any single battery and a 30K heater by anybody, it will want about 10 amps when the fan is running. That will kill any normal battery before morning.

So, if you run that heater more than about 6 hours from a fully charged battery, it may go down.

If you come back tomorrow with more about your house bank and what the heater is, I can give you a more accurate answer. You may not like it any better, but it will be closer.
