Travelling Canada to Alaska and into.
I agree mostly with the above replies, but I might think finding and owning a 30 by 15 amp bone might be better, cheaper and easier to find. Therefore make a train of surge protector, 50 to 30 amp plug to post and then 30 to 15 amp to post, if required. Again with 15 amps you are not running too much with your Vista 29. Just did the Yukon to Alaska last year, plan ahead it will be busy this summer. We had no problem with power, water or sewer, only a few nights of dry camping but watch out for old gold dredge teeth flower pots.
Do not forgot about securing your surge protector with a lock and cable to something, they are valuable.
