Do I need a Generator?

When I had a TT and boondocking like at quartzsite and had my PU unhooked. I would pull my PU front end up to batteries and use jumper cables to PU to charge my TT batteries in the morning. Charges them fast. When on the road parked overnight with no AC I started my PU in the morning and let PU run while we ate breakfast charging the batteries. If you have 2 batteries you should be good. Camp for a while to see what you need. While off the grid I found that a portable solar panel worked well also. Granted you do get spoiled with a generator and having an electric coffee pot, toaster, and microwave off the grid.
