Thanks for helping me calculate what we'll be needing for 4 nights and 5 days on the road this upcoming trip. The tanks appear to be two 20lbs.
Yes, the sine-wave inverter is on constantly, and it has been for about 5 days but we don't have full-sun and batteries seem to be charged fully, and simply keep equalizing at this point.
Thanks Gary, Denmark, and Greg for the recent in-put, because it made more sense to me when trying to decide if I should purchase another heat-source. I decided to keep the small electric, fire-place heater turned on during the night, and let the propane kick in when the furnace feels the inner temp gets too cold. We will be in Saratoga, WYO and the night time temps will grace 30, I'm sure.
Gary, the up-grade includes the sine wave inverter, two solar panels, and inside there's a small dialogue box that shows a steady, red light or the light is blinking in intervals depending on batteries charge. It set the last guy back @ $1,800. If I'm informed, I am realizing the solar is only a way to keep the batteries charged up, not much else, but that could come in handy without any electric hook-ups around. I still can't turn the lights on after it being on for 5 days, so that says something too. :-[ Kind of Embarrassing.~Karen
