A BACKUP TV set from Audiovox at Crutchfield. Camera and screen are individually powered wireless from a two female plug set from Walmart/RV. The
Audiovox is radio transmitter camera, screen receiver, no wires but for 2 12V DC power cords.
Ford E250 Tools:
7mm socket for door panel screws (4) upper left, 2 at inside door handle, one bottom panel right.
6” long ¼” drill bit, one regular 5/16ths to fit ¼” stainless steel threaded rod, one 1/8th” short to start outside hole.
One piece 90 degree triangle cardboard from a cardboard box used to insure straight drilling thru door panel from the outside to the inside.
Vise if available or vise grips, two pieces wood for bending strap in between either clamp or vise grip tight then pull up and turn with 2nd vice
grips.
A washer under the threaded rod mounted as a permanent stud on the door is better with another strap, probably painted to match, for spreading the
nutted rod’s compression on outside door panel, which is thin.
Locktite. I used red locktite which is unfastenable without heat or force at the ¼” level but more expensive than blue locktite available at walmart.
Idea is red locktite one end threaded rod/nut and blue loctite the other nut. Blue on both side is OK but harder to screw down.
The hole into the mirror fairings underside accepts the 12V camera power wires. A hole drilled above and to the left of the dark hole seen in inside
door photo, and thru the panel will open into the space inside the fairing inboard the hole you see above the bracket on the outside photo.
I have not selected male/female connectors: planning on removing the camera, unplugging connectors, pushing the female inside the hole, leaving the
threaded rod/bracket assembly on the door.
Redoing the aluminum strap with steel when I find a vise.
Using two hole safety nuts or star nuts is possible: ask the hardware man
With the camera mounted forward, the road’s edge is very clearly seen in relation to the right front wheel’s hubcap: no guessing. The road’s edge
streams toward the wheel cover.
Mounted rearward for LA/San Diego merging lanes,like removing a very bad tooth. No longer necessary to remove eyes from the road ahead, focus over to
the right side mirror waaaaayy over there while the garbage truck directly ahead slams on the brakes.

MORE Picasa photos at the BERM TV LINK, first post
BERM TV with a new bracket. See the wheel on screen ? Wheel should be screen located near bottom frame with enough vehicle side for clear
understanding. Notice the right side os now on the left side of your brain.
Taping or painting the screen’s frame at the wheel position would help your brain pickup screen-berm information.
The extra holes in the bracket’s body mount leg allow for vertical screen adjustment for wheel placing.
Bending the down angle with the out from the body angle is an acquired skill. Aluminum is taffy like. First try bending a bit from the middle past the
body angle bend, then out at the margin away from you and further along the strap, then at the margin nearest-forming the compound angle in several
bend motions in different bend areas-not one pull-the strap will tear.
The two screen images are not as sharp as what I see while driving. Photo taken at twilight.
Mounting the bracket against the strap washer takes two external tooth lock washers either side bracket and one inside.
When I find out where to drill the fairing for the camera’s wire-from an expert-I’ll post it.

CONVERSATION on Berm TV is: 'HELL BOY I DRIVE AN RV TO CABOS BLINDFOLDED,' or "why bother, my RV has one built into the side mirror."
Good questions ! I agree.
Despite that, Berm TV may be useful for pulling off the road onto what berm there is when a convoy of RV or commercial vehicles approachs.

the screen is too small to see much
