Hi Don & Mary Ann,
You bet, there is lots of ways to go from 50A to 30A. Here's a link to one of them.

That's Camper World in the US, but a local RV store in Langley should have one. Our dealer (Fraserway) gave us one when we bought our trailer. I also made a 25' 30 A cord into 50A to 30A adapter. beats pulling out the 50A monster cord
when it's not necessary. Hope this helps.
