Borrowing my Inlaws toy hauler, shore power plug question.

[Talisman61]

Borrowing the toy hauler this weekend since I wont have my TC done in time for Rally on the Rocks.

They've never hooked up to shore power, and the adapter they have doesn't fit.

Here's the plug on the TH

Will THIS adapter work for what I'm looking at? The power center is a wfco 8955pec so I believe it's also a charger. Plan to use shore power only while getting it all loaded and ready to go.
Thanks all!!

Instead of having a built-in power wore (RV to shore power) quite a few have a large, yellow (color)external power cord that the owner plugs in both ends.

It should have come with the RV. Perhaps in a storage bin somewhere?

Just FWIW....g'luck !
