Lawrosa, you're reinventing a wheel. You already have 30A outlet on your TT.
All you have to do is to plug that long yellow cable into it. Disable the converter and make sure fridge is not in Auto. The other end is plugged into inverter through 15M-30F dogbone adapter. Like Soundguy and others suggested.

Yes but the invertrer will be inside the pass through storage. I dont want to just have the cord running through a open compartment door. I want to be able to shut the door and do a professional install.
Boy, you sure are intent on making this much more difficult than it really is! :R Drill a hole in the cargo compartment floor, run a cable down through the floor from one of the inverter outputs to the outside world, seal it with caulking, and you're done. With the inverter located in the front pass through you'll have to also run cables down through the floor and out to the battery anyway, what's the problem also running the inverter output to the outside world as well? :h
