I have never been so frustrated. Last year I won a 18' Grizzly Tracker, 9.9 Merc motor and EZ Loader trailer. I have a 98 Jeep Grand Cherokee, and have been trying for weeks to get a hitch and wiring setup. *sigh*<br />To make a long story short, I got the 'certified Mopar wiring harness' installed by the dealer, but they won't touch the hitch I installed (Reece class II) cuz it's not a 'certified Mopar hitch'. They say it isn't safe, won't be enough for the boat and trailer. <br />My question: How can I tell what size hitch I need? I thought the class II would be enough. I can't find the paper work for the trailer, but it's classified as Y11. The registration doesn't show the weight. And I can't find the weight of the 1860 Grizzly either. Anyone out there can help this poor girl?
