A few years ago I wanted to make sure I'd have a back up in case my battery in the Jeep died at camp. Well, that never happened but if so it would be a long walk down a dirt road to any kind of civilization. I have an interest in solar and installer background so it didn't take long to realize and use the potential of solar energy. Quiet power, reserve power, no noisy genney running or extra fuel required, no fumes. The price of lantern fuel is nutz, & what 6$ for a set of 1lb propane canisters. Then there's ice - what's that have to do with anything - well there's the cost and a few bags of ice will only last so long.
The solar system eliminates the ice issue, no more soggy foods, gone is the extra plastic & metal trash. The older I get, I've found the more that bothers me. Anyhow if you got 10 minutes - enjoy.
