Very good question Wheels that would go along with my question about the water remaining inside the trailer frame.
The first boat I had the trailer frame was made with open channel frame and every thing would be dried out by the time I drove home from the lake.
My current boat trailer is of closed box frame construction and I can tell you that the inside of it can stay very wet for many days after setting in the garage.
So how does one get the inside of the trailer frame dry on trailers with the closed frame construction?
I would venture to guess that the majority of all water craft trailers are made with closed frame of either box or tubular types.
