Yea, definitely led's will be a big priority for me. Like I said, when we are dry camping we will try to conserve as much as possible. Lights and water pump will be the primary use. I learned with the pup that the furnace will drain the battery fast! If the weather is such that we will need heat, we will be looking for hookups.
One other question. I just read on one of the other threads that just the fridge 12V control panel and the CO detector will use about 30Ah per day!?!? I find that kind of hard to believe, but I don't have any experience with that since in the pup the fridge didn't have a control panel. Dry camping was propane only for the fridge. Also I pulled the fuse for the CO detector if we weren't using the heat. In the pup, it truely was just lights and water pump. I definitely need to find out how many amps the fridge will use when on propane, because that could completely change my calculations.
