I have one of those 4x8 kit trailers for my 10ft boat. It has eye bolts between the bunks that I use for strapping the boat down. I run the straps over the boat frame. When I bought my boat I was told that it's best to take it apart for long trips to reduce wear on the tubes from any rubbing that comes with road vibration. I haven't gone anywhere more than 1.5hrs from home and I haven't noticed any wear on the tubes from it.
