Fred F... Let Me Get This Right...
You have a sailboat with all kinds of 12 volt stuff, inverters, pressure pumps, mobile heads, communications gear, and for a break, you drive 300 miles in a motor home with 12 volt stuff, inverter, etc? I guess once you've figured out all that stuff on a boat, a motor home is just one with tires. And, I also suppose that 300 miles might not be as tiring as a 300 mile slog to windward. Still, Fred, we do wonder about you sometimes.... ;D Rick D.
