[JRTJH]

We have two 6 volt batteries, "free standing" generator, LED lighting and a 32" LED TV. We boondock in northern Michigan during the spring without problems. The temps drop into the high 30's most evenings, occasionally lower with most days in the 40's and 50's. That means the furnace kicks on every night, sometimes during the day. We "dry camp" for a week at a time using lights as we need them (not skimping but not turning everything on all night) watch TV for the 6 and 11 PM news. We usually run the generator for a couple hours every day between fishing trips and never have "battery problems". Our "limiting factor" is holding tank size and after a week, DW insists on a "real shower" and someone else's cooking, so I learned to "dry camp for a week, head to a full service campground for a night with Red Lobster, etc as a dinner diversion, then DW will "allow me" to fish for a few more days before we go home to clean the trailer, wash clothes and get the mail.

With 3 batteries and a small generator, you'll be set, enjoy camping with your grandson. Those memories will last a lifetime !!!
