Ok, to run that way, you need to pull the covering off of the bottom of the belly pan. That likely also involves pulling the stabilizer jacks. That gives you access to the holes in the frame and the rings that the wire runs through. This assumes that it runs fully underneath on your trailer. On mine it runs in the wall above the belly pan once it gets past the dinette. That means a pull of the inside aluminum as well.
Most trailers ( but not all, check the manual ) run a piece of 6AWG from the battery up to the dinette area. It's good for at lest 50A. That also may be all it's wise to pull off of the stock batteries......
If you are using the standard West Mountain Radio power pole connectors, they will not accept anything larger than number 10 AWG. Why you ask? Well Anderson rates them for < 30A. The guys in Norwalk decided to re-rate them to 40A. No, that's not a guess, I used to eat lunch with them on a regular basis.
The easy answer is to just tag into the existing cable.
