Thinking about getting a small boat

[Kern Dog]

All trailers (except the smallest box trailers) have to have surge operated brakes over here so they effectively brake themselves so the brakes on the car don't get much extra load....surprised it's not the same over there. I'm sales manager at a caravan dealer so have to know this stuff!

That is smart.
As stated, stuff varies by State over here. I hear of guys back East that have to have annual inspections of their cars.

Maybe that is because of the snow and rust that eats away at the cars back there. In the warmer and drier climates, you can find all kinds of cars from the 60s and earlier with rock solid metal.
