NHT, not sure about the rear end

NHT is correct and yes the 5.3 gets the bigger rearend, mine should be here anyday.

I also believe that the vertical camper mirrors are only available with the Max Tow - I don't think they are part of the package however. I also noticed that when you build one on the website the mirrors show up on the picture of the truck as soon as the Max Tow is added.
