I have owned my travel trailer for about 6 years now and (gasp) have never camped off the grid… until now. I have a trip planned that does not have access to electricity and my battery is shot. ...
Describe your "off the grid trip". One day? two days? 1 week?. What do you plan to use other than lights? Furnace? Water pump? Fridge? More info supplied will get you much better results. Good luck with your quest.
