I pulled a similar sized trailer cross country (NC to Yellowstone). My TV was a 2005 F250 Diesel. Only issue (just feeling it back there) towing was wind across Kansas.
My current truck is a 1014 F150 crew,3.5, LB and I'm looking for a trailer much like the ones you are looking at and plan to go across country again in a couple of years. I'm hoping to stay around/under 5000# dry and 27', so the Kodiak would be at the upper limit.
I towed my first trailer with a 5.3 Chevy, motor will do it, but as others have said, will be in high revs on any hills.
When we crossed the country, we traveled a 3-4 hours a day, which gave us time to site see at every stop. I would try and fill up un-hitched when possible. We had a diesel, so always looked for truck stops.
We also traveled allot off the interstate in the mid-west. Roads are long and straight with little traffic and great scenery.
If planning stays at major NP's, be sure to get a reservation if possible, we booked yellowstone 8 months in advance and had few choices then.
Have fun!
