Excellent thanks! Ok so do you think I should do something like this?At some point consider to have a GFI in the circuit as a van is considered a "wet area".
Inverter ---> gfci extension cord ---> outlet
with something like this?
Tower Manufacturing Corporation 2 ft. In-Line GFCI Triple Tap Cord Manual Reset-30396028-08 - The Home Depot
before it goes behind the trim to the back?
