Anyone who has owned or paddled an older OK Prowler 13 as well as the new ones: is there any difference besides color options? I ask because I’m in the market for one, and I found one on CraigsList that comes with accessories, a trailer, as well as a whole 'nother kayak for only marginally more than the Prowler 13 is brand-new. I’m thinking I can re-sell what I don’t want or need and end up with my kayak of choice for a steal…thoughts???
