Planning to take the grandsons boondock camping while the DW stays with granddaughter for girls weekend. Top pick at the moment is Sand Hills State Forest. It's going to be in late October so we may be wanting to run the furnace at night. I've tent camped a lot through life, but this will be the first with a camper with creature comforts. 1) Water pump, thinking this isn't a big power drain. 2) Furnace, no idea on the battery demand. 3) Lighting, all lighting has been upgraded to LED. 4) Electronics, 16" 12v TV (use doubtful), 2 tablets for kids daily reading and my cell phone all charged with the built in USB ports I installed. The battery is a new this year group 31 deep cycle. We will be camping 2 maybe 3 nights. I currently don't have any method of charging the battery other than shore power or connecting to the TV. Looking for opinions from experienced boondockers if I will have enough battery power without recharging.
