dry camping

Hanging a heavy quilt, blanket, movers pad etc across between the cab and the rear of the coach will keep the heat where you want it. A windshield cover also will help keep the cold at bay. We have two group 27 deep cycle AGM's and can go 3 or even 4 days without running the generator but our coach is very well insulated.

It seems easier to get the rig warm vs keeping it warm. Pull the shades and or use insulation on your windows and don't forget the overhead hatches. Stuff insulation pillows "available at any RV supply outlet} in to the hatches and you will keep a lot more heat in.

LED's can help but hardly worth the expense to replace ever light in the coach. We typically spend 13 hours a day outside retreating to the coach around eight. My bride journals for an hour while I read in bed and the two incandescent lights used for an hour don 't consume much power. The only big draw is the squirrel cage fan in the furnace, hands down the biggest DC power consumer in the coach but as it runs so little it is not a problem.

Most C's don't have a very large furnace which necessitates them running a lot, we got lucky with our Nexus as it came with a 35,000 BTU monster furnace. It only runs about 5 minutes an hour until we go to bed and drop the thermostat down from 72 to 65 for the night at which point it comes on maybe two or three times all night for 5 or 10 minutes.

Our thermostat is right above e the bed and when I wake up it is an easy reach to kick it back to 72 and retreat under th heavy blankets until it works its magic, usually about 10 - 15 minutes. All of the above keeps us toasty even when temps are down in the low thirties to even the mid twenties... below that we stay home.

Gee, I don't know, charge them?

Buddy heaters or other radiant propane heaters are great, have one myself, but even “ventilation” is not 100% sufficient to keep the moisture down in an enclosed structure.
Those things make a lot of water and a de humidifier is almost a necessity in a camper if one is used regularly.
For comparison, if I heat my 32’ enclosed trailer with the buddy heater (continuously, not just sporadically to warm up for a bit), the little heater will heat up a 250sf structure to room temp at slightly below freezing temps, but if it runs for a day or more without running a box fan and leaving vents open, the walls and ceiling are dripping. With the fan, there’s still a bit of condensation forming. Add the humidity of occupants in a camper and it’s too much moisture.
If in a dry environment and not where we live, it’s better but not a good solution for heating a camper long term.

Get a Mr Buddy propane heater and connect to your main propane tankes

Get an alternative heat source.
Lil Buddy or something like the Camco Wave heater.
Wave 3
wave 6
Buddy heaters

No fan or battery required, but you do need to provide some ventilation.

Install LEDs, conserve power usage, solar, catalytic type heaters, insulate windows.

don,t use the furnace use a buddy heater OR theres another one that claims its good for rv,s thinks its called camco olimpion. spelling is not right but close.

But campground rules often forbid using generators before or after certain times. Some have two 2 hour periods for charging.

furnace pulls lot of power need really good battery to do just one night.

Solar panels and a back up generator.
