INOP ESOF...
Sooooo, blizzard here at home 4 or 5 inches on the road and went to 4HI and......nope, nothing. Check 4X4 message with the wrench. 5000 miles. Sigh. Tuesday mornin appt with the dealer. Fortunately made it back to the house without too much trouble. Glad we weren't heading up the canyon...🙄

Did you lock the hubs in manually or do you leave them on auto and flip the switch?
On a side note, by "canyon" are you talking about that climb on the I80 out of SLC, that is no fun and I always seem to hit that at the worst time on my way back to Wyoming. I know the cutoff is available but I think it takes too long...

those hubs arent maintenance free and will require attention from time to time. although on a new truck you SHOULDNT have to touch them for a while.

So with the hubs manually turned to lock and then you use the switch on the dash the front end does not engage?
How did you verify? Did you crawl under the truck and see if you can turn the drive shaft?

Maybe check the transfer case electrical connection. At least get you by. Could just be loose. Should be able to hear the actuator try to drive. I hate that Ford did away with MSOF in 2020. Mistake IMO.
