Rear view camera cable routing

[montreal]

I got a nice Camos RV420 kit for the 310. It has a tiny camera which is heated, infra red and has a mic built in. There is a longggg length of cable included. There has never been a camera fitted it seems.
i sort of know where to install the camera but what route shoud the cable take?
I am thinking it has to run along the chassis rail and up through the the floor into the dash area.
Where does it go after it goes into the roof? I think I can get it into the cabinets over the bed where the clock is and route it to the right out of view. It then has to go into the side of the end cap but has to get to the floor.

I've read in the trailer forums about owners using a Plumbers Snake to wire stuff. Sure if you did a search, there's gotta be something in the forum. If I can find anything, I'll be sure to post it here.
