Glad to see I'm not the only one that suffered that route!
I ended up running a 1-inch flex tube from front to rear. Inside is the rear cam s-video cable, power cables for the rear winch connector and a 12v switched line (couldn't find one in the back of the truck).
I have a flew splices in the camera wiring so I hear your concerns about moisture and dirt. The splices were soldered and then sealed in shrink tube with a coat of RTV silicone around the tube edges/ends. At least I think they're sealed.
