I should add that when I first got my Dormobile, I investigated switching it from RHD to LHD. But after driving it around a bit, I decided it was not worth the effort. It is only an issue occasionally with a left turn in busy traffic, but if I have a passenger, it is no problem. Ditto for the drive-through window at a bank or restaurant.
The first time I had a problem was the day I bought it, when I drove over the Golden Gate Bridge. I had to unbuckle my seatbelt and slide over in order to pay the toll. Since there are no toll booths in Arizona, this is again a non-issue.
RHD has some benefits. When two vehicles are trying to pass each other on a narrow road, I can easily get real close to edge. In a Series Land Rover, since the engine and transmission are offset to the left, the right hand footwell has more room. My old LHD SIII had a cramped footwell, and the pedals were offset to the left a little too much.
Perhaps the best benefit is the looks you get. One day, while waiting at a red light in the left turn lane, a kid in a hot-rodded Honda Civic pulled up to the right of me. He looked up at me, and his eyes popped wide open. "Dude! Is that steering wheel on the wrong side? Is that legal?" I said "Absolutely." "Man, that is TIGHT!" He grinned and drove off. I think he is going to look at converting his Civic to RHD.
