Okay, Good job gettting all the needed info on the first post!
With that info we can go to the interactive parts catalog here:
https://catalog3d.winnebagoind.com/menu/Parts.htm
That lets us drill down to see the inverter may have two options but they both show located in the same compartment outside near passenger side rear wheels.
Whether it is best accessed from out or in may be a question to look over but this should give a start?
Good luck on the chase!
Click these snips for best view or go direct for the whole picture!
