While we found this works incredibly well with just two kayaks, the biggest downside to this model is the heavy 'pontoons' and need for truck or trailer. Less portable, and more heavy. Not much more weight allowance either. We find too many other advantages with the Standard Setup to go with this one, although it did work quit well. Nothing wrong with this setup if this is what you have. I'd recommend a higher horsepower trolling motor and larger or more batteries.
