Okay! First congrats on getting all the good info we need to begin to look! What a lot don't think about is how many different RV there are out there and even though they may know which they have, we are often left in the dark!
You got the good stuff in the first post so CONGRATS!
Info on the Winnebago site is set out year model and floorplan but you got it put in, so we can take a look. But I always like to let folks know how I get to the info in case they need more at some point.
Get to electrical drawings here to choose which RV:

Locate 2022 Minnie Winnie and 22M to get here:

Info is often sorted down to chassis for the things a normal truck might have and coach or body for the things added to make it an RV!
So you need to know about body/ coach 110 wiring. They often break things down to installation which is the drawing of where the wiring is placed in the physical RV. Like the wires run up this wall and across the floor here, type stuff. Good to have a drawing but not terribly useful if you can look at the RV itself.

Then we get down to the drawing that shows how the power gets from the plug to the outlets and that is kind of like a path to follow! Look down to sheet 5 for that?
Click on this snip or go direct to drawing if you want the whole picture!
Power comes in from cord, to the main breaker which passes it on to the other smaller breakers. Since you are getting power down to the GFCI, we can say that first part is good to that point!
There is an outlet outside that shows on the path to the bedroom.
But the idea is that power comes to the GFCI and then goes out to the next one and on down the line.
We can say power is good to the GFCI but we don't know if it gets out on the next wire going to the outside?
If electrical is a new thing to you, it may help to think of this as like a line of sprinklers and hoses connecting them. We know it gets to the first one but why does it not get to the rest? Gotta look for a hole in the path!
If new at this, pull the cord or click the breaker off before trying to look at the wires as a safety idea! Not to burn the fingers, etc.!!!
Good luck in the chase and do let us know if that solves it?
EDIT: Reading again, I see I missed what you said about the GFCI and I thought it working. If not working, check the breaker and also there is a good chance the GFCI is not reset and holding. It is a thing that wears out pretty quickly and pressing in on the reset may not hold.
Somedays I have trouble reading!
