He may be running his generator to split water into hydrogen and oxygen which runs the motorhome. So basically that motorhome is a hybrid. a Gasoline generator to hydrogen and oxygen to run the main engine hybrid. So for whatever it costs to run a small gasoline generator he is driving down the road basically for free beyond that. Join them. How else are we going to survive these gasoline prices?
