I was reading the www.aventuresports.com web page tests. They essentially say that a pro pioneer can haul 1000 lbs of gear compared to 500lbs in a aire traveler. I am wondering how this can be? I believe the traveler is about the same lenght at the water line, 4 inches narrower, and a much thicker floor with the same diameter tubes. Is this creative advertising or is the pioneer that much better?
