these are the pictures of the Inverter install in our Montana

back of bed sidewall with box and reinforcing plate installed
Plug in finished
I can now run my CPAP machine without being plugged in. I have a Genset box in the front so I use that for a dirty area and reinforced the wall with 3/8 plywood. I would suggest that you cut out the plate for the sidewall first as after I first installed the box I then realized it needed reinforcing. Total cost approx. $60.00 I bought the Inverter for $35.00 for amazon.com the first one on this website is the one I got.
