Another alternative here since I only haul one boat and some fishng kayaks. I got a good chassis at an estate sale. Had Maypop tires but I got it home OK. Added new hubs, lights, tires plus spare, shortening the tongue and added cross arms and I'm in business for about $375 total. The cross arms are scrap street sign posts I got from the city public works dept., 2" galvanized with holes every 2" which cuts a lot of weight.
