In Minnesota I saw the results of a fishing boat/trailer without brakes jack knifing during a panic stop for a moose on the road. Nobody was hurt but he bent the heck out of the trailer, boat and the back of his pick up, the poor guy had to rent another boat and lost half his vacation getting his trailer welded back together so he could get everything home. This was about a 16 ft boat with an outboard so I'd guess he was less that 2000 lbs.
My toad is under the legal limit for brakes but having seen the damage a little boat could do, I went with a brake buddy.
