Yep, like I'm sure every one else has said not much difference in the capabilities. You don't mention what you plan on towing with it. My 'mentor' in this RVing experiment told me without reservation, buy the trailer first. You can always find a truck that will carry a given trailer, but not necessarily the right trailer to match the truck. I did not want a dually as my TV and had already found a number of 3/4 and 1 ton pickups... Same guy used his pickup to tow my trailer to a campground where it lived unit mid-summer.
1. His recommendation was spot on, my pin weight, came in like ounces under the max my current 1 ton dually.
