It better be cheap, like under $100. One of the things a
travel trailer owner takes pride in, is being able to hitch
up. Once they get the hang of it, it's simple. I don't think
there many instances of damage done to either driver,
MonBack or equipment.

Hi,
Well in that case it better be cheap, because there are mirrors that
you can attach to the back of pickups that do the same thing for under
40 bucks for one.  Two, once someone gets used to hooking up a trailer
they use something on the trailer as a reference point and can usually
get pretty darn close.  Three when backing up to hitch looking at a
monitor rather then at the rear view mirrors might make matters worse.
Four a backup warning device like a siren or beeper can easily be
attached to the backup light circuit to warn people. Five,it would
have to have a really wide viewing area to the sides to be able to
tell if anyone was in the way.  Six, there are cheap wireless camera's
available now from places like  that could tell you if you have the
ball under the hitch.

Don't know how many sales you would have but you never know.  Backing
up travel trailers and 5th wheel trailers has some dangers involved
for sure.  But because of this *most*, not all for sure, owners are
really careful when hitching up.  Risk of injury to loved ones and
damage to an expensive trailer usually makes folks cautious.

While pitching it as helping safety and reducing damage to vehicles
might be true, it would be more of a convenience item, IMO.  Remember
when you think you invented something that doesn't exist and it's not
*completely* new, all you really did is find a different way to do
something or use something, which might only be one way of several
ways to accomplish the same thing.

Risk vs. Rewards..... If it's cheap enough and unique enough then the
rewards might outweigh the risks.

Good luck.

Take care and Happy Campin...

Well, I am sure you thought of this, but I'll add my 2 cents anyway.
The problems that I have observed are as follows:

1. When disconnecting, people forget to chock the wheels of the towed
vehicle, therefore, Trailer rolls into the vehicle doing the towing.
Or, Vehicle rolls away from towing vehicle. Either way damage can be
done can injury can result.

2. People back-up too fast.

3. Mon-backs (guiders/backers) don't stay in the proper position so
that the driver can see them at all times.

4. Mon-backs don't look up when driver is being guided backwards,
therefore the top of the towed vehicle is vulnerable.

5. Driver don't realize the postion of the front of his vehicle,
therefore front bumper hits something/someone.

6. Hitch isn't on the ball correctly.

Being a retired Firefighter/Paramedic for 27 years, I have seen the
result of most of these. It all boils down to knowledge, concentration,
experience, proper training and common sense. The biggest problem is
common sense and that can't be taught. There is no safety item/aide
that can overcome the lack of common sense.

Good luck,

Hank <~~~has an occasional lack of common sense too.
