Use lights and water pump sparingly to save battery. Get a f ew led's for most used lights. Or a few led dollar store push lights. 2nd battery would help , even if it's just in the back of the truck to swap when 1st one starts to weaken...you will know cause the propane sniffer will start to beep. Bring battery operated radio. Those solar garden lights work to, outside or even inside.
Battery has to be decent to run the fridge on propane.
It was a rainy few days at Algonquin Prov park...tarps kept us dry.

We only dry camp and we always bring a battery powered radio and flashlight. Dual batteries helps furnace last longer. But what we find we use the most in the mountains when dry camping is a fire ring for our campfire ( I use a 24" chunk of culvert) and I flip a picnic table upside down in the truck bed to take along so kids and grand kids have a place to sit during the day.
