Hey a buddy turned me on to this.
Has you or a friends trailer ever not played nice when it came time to back it in the water? This device magnetically sticks to trailer and holds itself in place so the trailer will not lock it’s brakes if your reverse lock out has refused to work.

I’m gonna make sure my HOA’ S launch ramp has one of these on hand, come summer time some donkey is always blocking the ramp because his or her brakes are locked up.
P.S I tow a like 5 different boats/trailers and on my old truck their was always a trailer in the many I would tow that would blow out the trailer reverse fuse. It became so common I would keep extras on hand and I would even label the fuse, so I could spot it in a instant, it was a quick way of avoiding delay when your trailer decided to protest
