scary thing about a locrite on ice is it will lock when it feels that one tire is spining to fast and not grabbing traction and it will do this at once without you knowing when and its very rough when it locks and it could throw you off the road( not my exp. i heard about this from a friend of a friend) if i was you i would look for a selectable locker or Elocker yes they are way more expensive but when you need it its just the push of a button away or switch. no the the advance trac i would go to ford and talk to some of the mechanics and get their 2cents on what they think of that. no offense to anyone here but on a truck that new i would be at ford alot to make sure i wasnt going to throw money into something that could cause me to trash my new truck. this is just my 2cents so take it for what its worth. good luck with your truck
