You would be wise to set aside several hours to just read the various posts here on the forum, make notes, or print out stuff to remember. There is just so much to know about how the water, power,towing, tires, etc work. I believe the inverter also drains a small amount of battery as well. I take off the negative lead and the battery keeps a charge really well like that, all by itself. I put it on a trickle charger at times, just be sure to check battery water at least monthly if you do that.
