Called McGard and they sent me a new key to get the spare down! That allowed me to get the full-size spare put on and ready to go! Woohoo!
After that, I spent a couple of days installing the AirLift kit on the F-250. I ran into some issues being that my truck has a BW turnover hitch installed in the bed. That meant I needed to remove the side plates to allow me to access the frame where the airbag mounts mount to the frame. I went to everyone's favorite hardware store for quality tools, Harbor Freight (lol), and got some big, big sockets to allow me to remove some big, big bolts.
It took me a couple of days of work doing it all alone, but I got it in and they work great. Another set of hands would have made the job a bit quicker. I am confident they will level the truck when the camper is loaded and soaking wet in the truck!
