Thats a big trailer, but a congrats is in order first, I have seen just what your going to do many times out there on the road, now you can expect the weight police on this sight to pounce all over your post, so what I am saying is your truck will pull it fine, but dont expect to be the first one to the top of the pass, you also may find some "chucking" between the trailer and the truck, as in your trailer will be pushing your truck, sort of a back and forth motion that you will fill in the cab of the truck, have fun and enjoy yourself and dont let this site weight police get you down
