I think I'll check out the Facebook group as suggested. I have about 2800# of capacity available for the loaded pin weight. At the 337's max weight of 13995# I will be right at the 22000 GCWR for my truck. So I can do the total package weight but if the pin weight is too high I will have tire overload issues. I wouldn't worry about being a few hundred pounds over on the tires for short trips but when running cross country (1000+ mile trips) that's a whole different game.
So how does everyone like their GD? I am planning to do a factory tour next month. The factory is just 100 miles south of me.
