does the outside gfi box control the boxes at the galley and the bathroom
I don't know which model 09 Adventurer you have, but if you go here: Wiring Diagrams, select your coach model, and take a look at the Body, 110V Wiring Diagram you should be able to see where your GFCI outlets are located and which other outlets are controlled by them.
(It would be good to add your model to your signature line to help folks trying to answer your questions.)

Fastest way to find out is to hit the test button and see what turns off. If the outlet does not reset afterwards then it needed replacing anyways. Most folks don't test their GFI's monthly like they should (yes they should be verified every 30 days) so now's as good a time as any to find out what it protects and if it needs replacement.
“The great thing about GFCIs is that they protect you whether or not your wiring is grounded,” says Bill Grande, manager for safety products at Leviton, a manufacturer of GFCIs. Because lightning and other power surges can damage a GFCIs delicate circuitry at any time, Grande recommends the following monthly test: Plug in a light fixture and turn it on. Then push the device's test button. If the light stays on, the GFCI needs to be replaced.
I see from another posting that the OP has a 32H, so here is the correct Body, 110 Volt Wiring Diagram for his coach.
It looks like there are two GFCI outlets. The one in the Bath also controls the outside entertainment center outlets and the outlet at the passenger-side dinette (if present). The one in the galley also controls the outlet at the driver-side U-shaped dinette (if present).
