Like most topics there is some debate and lots of opinions. Personally I think you will be fine. You can always decide on aftermarket modes once you have it.
And I agree. I would make different choices in truck models than some folks, but I think that may reflect the struggle between having an easy riding daily driver with an empty bed and the desire to haul a big camper occasionally.
My two cents
