Pretty basic but we dragged our small inflatable up a steep, gravely beach and it was so easy to pull. Big inflatable wheels made the job easy. We just left the wheels down and drove around with the wheel assemblies under water. Slowed us down a bit but we don't plane anyway. As mentioned in other reviews, the metric fasteners were junk so I swapped them out for 1/4, 20 bolts ans used castle nuts to finish the bolts.
