Preparing to join family this fall in the Midwest, and have a question: thought I'd discover if any of you all may help. I'm thinking that some of you (?) have their 50amp rigs housed beside your home/garage when not in use, and have already addressed the question with plugging your 50amp RV into the 220volt home/garage receptacles. In year's past, we traveled in a 30amp Class C RV and could just plug-in at arrival at a correctly fused 110 volt outlet at the family's home/workshop at their ranch. Used one of their workshop outlets as this was traditionally used (and fused) for running all kinds of compressers, generators and tool-stuff. (They run a heavy equipment repair business). Now we travel in a 50amp Class A RV. All the 220 volt equipment and plugs (at their workshop) have what they call a 'crowsfoot' configuration...3 slots. Do I just need to purchase a 'configuration adaptor' to fit our RV 50amp cord plug (one prong, one L-shaped and two flats), into their 3 slot 220volt receptacles? I wish to arrive with the correct plugs/cords/adaptors... Thanks for your insights folks.
