Re: Van out of winter storage, starting to add a backup came
I originally had my rear camera mounted in the license plate area. This provided a great view for parking and backing up, but when I started using a hitch-mounted bike rack the view was almost totally blocked. I ended up moving it up to the penthouse, attaching it with double-stick molding tape to the top-mount brake light. This position has proven to be pretty good, allowing me to see both the bikes as well as the area behind for parking.
And, as others have posted in the past, when the penthouse is up you get a birds-eye view of the campground if you want!
Mine is hard-wired, and I ran the wire inside the canvas where there was already a wire for the third brake light coming in. I then took off most of the decorative trim for the penthouse where it meets the roof inside and just hid the wire in there, dropping it down at the driver's side b-pillar.
