With those activities, I would personally stick with an LT tire.
I just put a set of KO2 on my truck and they are great. They have improved over the originals. I really didn't notice any noise increase over the stock highway tires. Stiffer obviously, but it's still a great riding truck either way.
I have also had a few sets of the Michelin on other vehicles. They are my go to tire if I don't need an A/T. They are quiet, smooth, and seem to last forever.
I don't think you will see much of a mileage difference between any of those LT tires. Maybe a 1-2 mpg increase with the Michelin LTX over the other 2.
