My F350 is used so little that the last time I changed it at 5000mi it had been over 2 years. Worries the dealer to death. It sits out there in the garage but I start it and let it run awhile every now and then.
I once bought a new truck that had been on the dealer's lot over 6 months. I suggested that they should change the oil since the oil change interval was 6 months. They made it clear that time on the dealer's lot doesn't apply to oil changer intervals.
I wouldn't crank the one in the garage unless I planned to get it well warmed up. You really want to cook out any condensation before putting it back in storage.
