I have the Davis, and for my situation, it's perfect. My dinghy storage area is fairly rough, and uphill. The large pneumatic wheels make all the difference. I don't even remove the outboard, which is a big plus. I just leave everything next to the dinghy storage rack until the next time I need it, then I just roll it down and launch
It's made my life a lot easier. Oh, I do all this alone.
