Are There Different 7-Way Trailer Wiring Connectors on RVs

Question:

Are there specifications for the RV 7 way plug and receptacle in terms of dimensions, contact types, features. I find plenty of wiring diagrams, but nothing like an SAE or ISO spec describing the sizes, etc.

Basically all 7-ways you see either for sale from us (or anywhere), or on the road are all made to the same size. This makes picking out replacement really easy as you know the sizing is correct and you don't have to check to make sure you have the right size or version of the 7-way. So the # 50-87-009 that you referenced would be a standard 7-way blade socket which would work well for you if that's what you are looking for.
