I only own a scupper cart, and it can be a problem to get it mounted without turning your kayak over onto its side. That may not be a problem, but I have a battery and other stuff that dumps out when I have to do this-it is a PITA. If you can get a cart that you can place your yak on without having to turn it over, then strap it down tightly, you might be better off. I can't keep my yak upright while getting the scupper rods through the scupper holes from underneath-it is almost a two-person task.
