I have a trailer that cannot be seen while backing it up to retreive my boat
becasue the tailgate of my truck to to high. The trailer is to narrow to be
seen in the mirrors.

I saw a boat trailer that had a pop up flag on a spring loaded arm which
popped up when the boat was offloaded and which when the boat hull ran over
it on trailering. Since it pops up when the boat is off the trailer, it can
be easily seen when backing up.


Does anybody know where I can find such a thing or what it is called?

Thanks
AK
