? On dry camping for 2 nights propane use?

I learned on day one with one group 24 battery. It was heavy raining and the pup was finally up by 830pm. Furnace cranking baby screaming you name it as the shyt hit the fan. ?i was going to trade that nightmare in the following week, kept it for two years and ATE $4500 on a trade. I bought a yamaha 2000w generator, popup gizmos, 12vt entertainment, reflectix mods, and became equipped to boondock year round in harsh north east PA conditions.
