Thank you for all of your responses. The information that was posted on the truck was taken from the door stickers I have attached 2 pictures as well. As far as the payload goes it will be me and my wife and 2 small dogs about 340#. As far as the hitch goes i was going to convert the standard hitch on the trailer to a Reese goose box and just use the goose neck ball in my bed. From what i understand is that the frame will be still covered under warrenty with this hitch set-up.
The Reese Goose Box is covered by Lippert, the frame manufacturer. About the only "roadblock" I can foresee is a probable "blame game" between Keystone and Lippert with who is going to actually pay for the repairs. It'll eventually get fixed if you have a frame issue, but it won't be a "one call approval" because both will want the other to pay.... I'd almost bet you are the one that's going to be "caught in the middle" until they decide who's paying. That means your trailer "sits on the lot waiting for approval" rather than "on the road behind your truck"...
That's only if you have a frame problem and the repairs get contested.
Now, just so you know, your truck is a "unicorn" !!!!!
I tried finding a similar GVWR in a F250 or in a GM 2500. There are none on any dealer lot within 500 miles (the search engine max distance) from Detroit, Chicago, Nashville, Dallas, Houston, New Orleans, Atlanta or Richmond. That said, your truck should have no issues carrying the load placed in the bed by that trailer....
A "consideration in your thoughts on how you pack for towing"... You "might stay below 1000 pounds of additional cargo" but probably not. Just adding camping gear, tools, cooking equipment, dry goods, and a jack/lug wrench (in case you have a flat tire) will consume that 1000 pounds or even more...
And, your intention to "always travel with empty tanks" might be the plan, but when you dry camp at a "pristine no facilities campground" what you take in you tow out. With no dump station at many of the "no facilities campgrounds" or even in some "on the lake campgrounds with a dump station" if they have an issue with the dump site and close it (happens more than you might think) then you're faced with towing with full tanks or sitting until the dump station is back open....
Things happen, ALWAYS plan for the worst conditions and you'll ALWAYS be prepared.....
Bottom line, I think you'll be "good to go" with that truck/trailer combo...
