Be very careful wiring up your house for the 30A and 50A pedestal connections. They are slightly different than regular house wiring... A mistake here will get very expensive for you when you first plug in... Lots of blue smoke...
Even when you have a professional do it can be dangerous. They too should be mindful this is for an RV Circuit. The savings grace with using professional electricians is they have Insurance to cover the blue smoke mistakes. If you do it yourself guess who pays for all of that haha...
The 30A RV receptacle is indeed unique, and is the one that sometimes gets miswired with disastrous results. It looks vaguely like the (older) 3 wire 30A 240V electric dryer receptacles that are quite common, but is not the same thing and is a 120V connection.
The 50A RV receptacle is absolutely identical to a (newer) four wire electric range receptacle, and any electrician with any experience at all should be able to properly wire it in their sleep. You could unplug your kitchen range and plug your RV in, if it isn't a three wire range connection; or, I suppose, bring a range to a campground and plug it in there. People may think you a bit odd, but what's the fun in being boringly normal?
