I encountered a lady who was in the market for a new motorhome. She didn't trust gas and wanted all-electric. Cooker, microwave, shower, the lot. It was explained that this would only be possible with a hook-up, and even then might be problematic. That wasn't good enough. She wanted to be able to wild camp, and run everything from batteries. A generator was out of the question apparently; too noisy and smelly and anyway who would make it go? I should mention this wasn't the sort of price bracket where a built-in self-start genny was even remotely feasible.
