They are electric, Barry, and the electric components are on the steering column. I cannot believe that they are not waterproof either but I think they are just covering their backs against people who store them outside. They had the same model as ours outside the showroom and it was raining. No one moved to take it in or cover it up at all. I will bring it up with the lady who has been motorhoming with hers for about seven years. She had her motorhome converted so I assume it is in the garage a lot of the time.
