Fifth Wheel RV Refrigerator hooked up to inverter

Double check the line as I have seen copper in wheel openings. I also thought move the line but with how cheesy the RV builds are they probably boxed themselves into a corner and had to run it out there. Seems crazy to me but again, it is an RV.

But....then again how many times have I looked at rigs and thought why would they do that when they could have done it this way? These are not engineered like our automobiles.
