Default Backup Sensors

Has anyone had any experience with using backup sensors to detect how close they are to their trailer while backing up the combination, in particular while backing around a corner or into a campsite. My depth perception in determining how close I am to my trailer in these situations is getting pretty bad and as a result the front of my trailer's V nose and the rear bumper on my 'Bird are paying the price.




The damage is repairable and I plan on doing it but I'm also thinking about installing a set of backup sensors on the rear of the 'Bird under the bumper, but I'm wondering how acurate they are at determining the distance between the bumper and the front area of the trailer as it closes the gap while backing up at an angle.

If they are like the ones on our Lincoln they go off at about 3 to 4 feet.

It may sound primitive but for awhile I used squeaky toys attached at the points of contact, the bigger the better. I used footballs that squeaked on impact. They're not real loud, though, so a test squeak would be in order.

When sitting in it with the stereo on and Roberta moved the trash barrels around behind it.

On my wife's new car they are adjustable, and she can get the side sensors about 6" from the garage post and the front & rear almost touch the wall.

The sensor kit that I have been looking at is also adjustable for anything that is already mounted beyond the sensors on the back of the coach such as the ladder and it can detect from 6 feet to 1 inch with both a visual and audio warning that changes the closer you get to the object (trailer) it has 4 sensors that all have separate reading on the gauge.

It is made in China and on EBay sells for about $37.00 http://www.ebay.com/itm/260932018448...84.m1438.l2649 . I have already contacted them to see if the wireless transmitter will send a signal 35 feet and they say it will.

The three wireless cameras that I already use on the trailer hitch, in place of the original rear view camera and the back of the trailer have worked great for me and they were also made in China, because of the low cost of this system I'm going to order it and give it a try, if it doesn't work, I'll mount it on my ATV

I had also thought about mounting more cameras and split screen adapter for my flat screen TV, but they would not work too well in the dark, so that is why I'm going with the sensors.

Mike as you can see in my illustration below, I'm more concerned about how close I am to the trailer that I am hitched up to while I'm backing up at an angle around corners.

I use the original position rear view camera to get close enough to the trailer when I'm backing up to it and then I switch to the hitch view camera to complete the hookup, it works great that way. Then when I'm ready to go down the road I switch to the trailer rear view camera and I'm all set.

All three cameras are wireless and operate on the same monitor but are activated by separate switches;

1. Original Rear View camera position is activated by the original switch.

2. The Hitch camera is activated by the rear Parking Light switch.

3. The Trailer Rear View camera is activated by a wireless switch and remote.

coming in at angle as you are showing,...with my sensor-that the most unreliable they are(thats how i have to back into my garage at this time due to some work we're doing and they go bonkers). also have trouble if there is something just to the side of where your backing to..sometimes if it's close enough they go nuts if i can back up straight there pretty good i don't know if all are the same as mine -this is the only experience I've ever had..sorry i cant be of more help.
