Where is GFC located for '90 Georgie Boy Encounter?

I have a '90 Encounter that when a faulty unit was plugged in the outside outlet, the 20 amp fuse was blown, replaced, but I need to know where the GFC reset is
located. The outside outlets, the coffee maker, and the outlets in front of sink still doesn't work. I am at an
impasse. I know it a simple fix, I hope.
