I've been doing a lot of research on beefing up my electrical system, and next week, should have had a Voltmeter, MPPT Controller, and 4 Battle Born Lithium batteries installed. Likely future addition includes another 340W in solar, perhaps more, as I've got plenty of room...

My system, once complete, will include 4-100Ah Lithium batteries, 600W Solar, 100A MPPT Solar Controller. I have a DP with 8K Generator.

I got to thinking that, since my goal was to better prepare for likely dry camp or boondocking adventures, when heat is needed, what's better - heat via Propane, or, electrically via shore power switch? Don't know if the latter can actually run and heat the MH, and if it can, do I have enough power to do so?

Use your Propane when dry camping. We use a portable heater when hooked up since I can't stand the sound of a heat pump turning on and off.

Propane for heat For heat when dry camping

Electric only if you have shore power and it's not too cold outside

My rule of thumb is save your batteries for those items that require electricity, use propane where it is optional. Heating anything with electricity is a big power draw. Something to consider is if you heat with electricity and if cold enough to freeze will your storage area get heat.

Unless you have a rather large solar field and about 3 tons of batteries

PROPANE

1500 watts is 125 amps at 12 volt. So a pair of GC-2 last. less than 1 hour.

If you had enough solar during the day you could possibly offset the propane use but a night use the 12v furnace.

I have run my fireplace heater for stretches, turn the fridge over to electric from propane during the day but there is 1,280w solar on the roof.


12v 500ah (5,120Wh usable) , 20 cells_ 4s5p (GBS LFMP battery system). 8 CTI 160 watt panels (1,280 watts) 2s4p. Panels mounted flat on the roof. Magnum PT100 controller, Magnum 3012 hybrid inverter, ME-ARC 50. Installed 4/2016 been on 24/7/365

400 AH is 4800 WH. The most common electric heaters of plugin sort are 1500 watts. Just one of them will exhaust your 4 LiFePO batteries in just over 3 hours. Add 8 more of those batteries to run that heater overnight.

We use a Big Buddy to heat our RV. It is much more efficient than the furnace.

I do use a heating pad or electric mattress pad when dry camping.

If you have 6 to 8 hundred watts of panels then an absorption fridge may be run during the daylight hours. 24 hour consumption is about 5.7 KWH.
