Not quite with you on what things are called but I "think" this will help.
Full wiring drawings are here. I think first page for your RV:

I cut the clutter and did some marking of what I expect the problem to be.
Click these to get a better view.
The power should come from the load center on the breaker as marked in green and go to a GFCI that may be tripped, or the breaker itself, so check those.
The items marked in blue should be checked to find which work and which are dead as a way to find where there is a "hole" in the line.
If it is all, then the main supply route needs checked but if it is only some, look at the spot where that supply should travel to it?
Think of it as a roadmap but there is a big sinkhole along the trip!
