Years ago the campground where I spent many a weekend decided to start charging extra for electricity.. now on a hot day in August I' might well spend 11.00 for ice.. But they wanted 4 bucks for electricity.
So I went to Sears and got a small Fridge (Doorm/office size) for 100 bucks (This was a LONG time ago) and never bought another ice cube/block from them again.. Plus the food came out of the fridge nicer.
Sold the fridge for 25 bucks when I got the class A.
So they got 4.00 a night for power.. And I saved 7.00 a night.. Got better food, and well, 10 nights (And I used it way more than10 nights) and the fridge was free.
