We will have 48 hr of boondocking so need the battery to last that long.

Propane. The only way it will run on 110 (electric) is if you have a REALLY long extension cord or a large inverter hooked up to multiple batteries with solar. I would recommend the propane route.

Propane. Electric is when on Genny or plugged in somewhere.

Even on propane your refrig requires 12v to operate. Factor that in to your usage for 48 hours. While you are driving your 7 pin does not really charge battery enough to make a big difference unless you were driving for a "long" time.

propane for everything - fridge, water heater, etc. depending on how far you’re driving you may consider turning the fridge off until you get where you’re going. To NOT run the furnace if you only have one battery. Do you have a generator to take with you to charge the battery if needed?

on pp your frig uses very little 12v , you should be fine. BUT the furnace eats 12v. will kill a battery in a few hours. and the frig really doesn,t use much pp.check water in battery clean post charge before you go. if your equipt is in good shape you,ll have a fun trip. don,t take care of things it,ll bite you in the butt just when you don,t need it.p.s air up those tires .

48 hrs is very doable if you watch your light usage and don't run the furnace.

no.

yes.

maybe.

Pre-cool the RV fridge for 2 days before leaving,

Switch to electric 12 volt.

Have assistant rev up tow vehicle engine to 2000-2500rpms

Look at voltage reading in the RV electrical system. If it is not over 13.6volts the fridge will gradually flatten the rv batteries while you travel.

^Fridge on DC will deplete RV battery either way unless a dedicated charging circuit is set up and verified.
Run it on LP period. Don’t overthink.
Next question.....
