This is the original trailer I used until now to haul my 27PC (28 ft 2 in long). I made it fully adjustable and should have just stuck with it, didn't really need another trailer but after dumping over 40K in the boat, I decided to get a custom fit trailer. The capacity tag on the trailer reads 12K pounds. My new trailer (if I remember correctly) is 10 inch shorter then the old one. Don't know how much it weights by it self.
My thought is the original trailer was a maximum load capacity 12K trailer. The 27PC being such a heavy boat they went from 15 inch tires (listed on the plate) to 16 inch tires and it has 3-6K axles. Don't see any way the trailer weights 6K, my guess is 4K tops.
So I live in far south central KY, close to TN
