I picked up an older Burley D'Lite child trailer a while back. The shoulder straps are secured to the sides of the trailer. With one small child in the trailer I don't think the shoulder straps do a good job of holding the child. I noticed that on the newer Burley D'Lite trailers, the shoulder straps are secured from above and go straight down to the "Y" buckle, much like a car seat. I'm thinking of modifying the shoulder straps in this manner. Has anyone tried this?
