I originally had an E Z loader very similar to that one. Last year I had to get a new trailer due to age and stuff, it was then that i realized that there were only "4" actual load bearing points on the trailer. The places where the crossmembers connect to the frame..My boat had been riding on just FOUR BOLTS the entire time I owned that trailer. I really feel like I was lucky that none of those bolts broke while I was on the road......
