I donno Dennis.  It seems to me that campgrounds that charge $5 or $10
per nite for electricity are out of line.  I know they have to pay off
the costs of installing the outlets, etc., but 100W for 10 hours is 1
kwh which costs about 10 cents in most markets.  Scale this up as you
like, but it's hard to justify the typical charge.
