Re: 50amp to 30amp adapter
I've only seen 50A in private campgrounds and usually in sites with full electric, water and sewer hookups. I try to avoid those mainly because they cost more. The vast majority of campgrounds have the 30A plug and they all seem to have an optional 15A or 20A plug as well. I suspect the same with a 50A site though I haven't been to one. That's just the way electrical boxes are designed. I carry a 30A to 15A adapter just in case. I use it when I visit a couple of private homes (out of necessity) and it handles everything except the air-conditioner.
