My question is where does that wire go once in enters the outside floor before it emerges 10 inches away inside the trailer floor.
You can't intercept them from there - if the next stop on the red wire is the battery disconnect, then it's already passed the positive bus. According to your Owners Manual this is located: under the front bed and riveted to the inside skin front plate.
This is where your batteries will need to connect to. There might be an inline 50amp breaker too on the red.
Likewise the white white wire is the line running from the negative bus that grounds to the chassis. I'm going to guess that's located near to the always hot positive bus.
Let us know if you find it.
