Schematic

On the 2013 RP172: Separate breakers for Main, A/C, microwave, water heater, fridge/power converter, GFCI. Six in all. The TV is tacked on somewhere.

I honestly didn't check the Microwave or fridge.  I'll do that this w/e when I pull the Pod out of storage for a local 3 day trip. After thinking about this, I'm hoping the GFCI gets it source thru a breaker / other than the main 30 amp.

I just found out last week, that All 120v in my Pod (including AirConditioner) goes thru GFCI outlet on the side of my bench seat.  All my 120v was dead, I checked circuit breakers, reset them .....  I just happened to look down to outlet where I normally see a little green light ... there was none.  I saw the GFCI, reset it and all was well.

Assuming the 171 is wired a lot like a 177.. if you look under the documents hanger in the bedroom, you will find a large access panel.. inside is the shower plumbing. and the wiring to the outside outlet and porch light and the "up and back" cabling for the TV antenna..

But again.. it's so simple you really don't need much documentation.. nothing in there is going more than 10 feet from where it started. I have trouble shot a circuit with my DMM from a sitting position to the outlet and back to the box..

The hubby just wants to KNOW things. He does not plan to get in and rearrange. His engineering back ground plus his years of flying and being a male, he wants in the KNOW. LOL
And we say all the time, what ever day or hour your Pod was built, the one before and the one after will be different depending what hand dipped into the parts area. We found 3 different kind of screw heads on our Pod for instance. The box schematic sketch may have done the trick, but it will come up again, I KNOW. My power distribution box is under the seat in dining area. I understand the dealer not wanting it to be messed with. All RV's , no matter the size or make, are screwy. Before buying our first motorhome years ago we traveled up to the factory and the husband crawled under one on the SHOWROOM floor. He did the same in a factory tour at BMW in Munich. The Germans are less tolerant if you get out of the marked path! So when asked, he has to KNOW.
