So glad I purchased the Dynamic Dolly for my Bonafide SS127. If you have a SS127 or SS107, and your little kayak cart, isn't cutting it... buy one of these Dynamic Dolly's. It's so much easier moving your loaded down SS127 or SS107, from the parking lot to the water. If you have bad knees like me, then you need the hitch mount also. Next best thing to a trailer. These Dollys are super strong and well made. Highly recommended 👌!!!
