New Truck and Tires advice

Either truck will be fine, if they come with those rims, u should be able to so call down grade to 18. With that being said the dealer can change them out and should not charge u anything since he's giving you a less desirable rim tire combo. Everyone wants those large tire rims now so it would be an easy sell for dealer. He would make out better with the swap for sure. A 1/2 ton will pull the trailer and even a 25ft without issues. I would look At both and see who gives u the better deal. I like the 6.2 so I personally would go that route. It's got plenty of power and you could get a nice deal since the new style model is coming out. Good luck keep us updated!!
