Good idea. I could never get reflective tape to stay, like @Verna but I have been sticking my bright yellow magnetic camera back there as a marker. The coupler gets list in the backup camera's shadows.
A neighbor of mine that has a T@B recommended this for TV's that don't have backup cameras. It is a bit spendy, but she swears by it. The viewing screen plugs into a cigarette lighter. Rear View Safety RVS-83112 Video Camera with 3.5-Inch LCD (Black)
The backup camera on my 4Runner is not on the centerline of TV and thus not directly over the hitch. Makes left / right just a little more challenging for that last foot.
Great idea! :o I've added white paint to my coupler but does not really help - - - I've also got glasses So it is not my eyes it is the backup camera! =)
Since I don't have a backup camera, I just use those magnetic stick things with the yellow balls on top. One on the hitch and one on the coupler and it only takes me a few moments to line it up and get it hitched. I do have those backup sensors and use the "beeps" to tell me when the hitch ball is under the coupler.
Our van backup camera is not directly in the middle (more on drivers side due to the hatch latch) so it is not as easy to line things up. I think we may need to try the bright yellow magnet trick.
I've only "hitched up" about 15 times now, and my backup camera on my car has been a lifesaver. On my last trip, the sun was directly behind the car, and completely messed up the camera! I wound up using a chock on the propane box for the "azimuth" and another chock for the distance I needed to back up (like Marknjudy…
Mine is spot on alone with the backup camera. I tried the two yellow balls on magnetic sticks just for some extra help (before I got really good at lining up) and I couldn’t find a flat place for the magnet!
I use my old GoPro 3 with wireless signal to my phone. All I have to do is strap the camera to the hitch of my jeep and backup. I usually get within 1/2" of being directly over the ball.
