No. Not in my experience anyways. The rear of the rack is the highest point as measured on my truck with no weight in the rear, to include when my safari windows are open.
I know this because I can clear my garage door by 1/2 inch and it's only closest at the rear (flat garage slab and less than 1% approach incline from the driveway).
After mounting my Leitner rack I had a friend on a ladder observing and filming as I inched back into the garage for the first time. One of Leitner's reps actually suggested that I give up looking for a rack if I want to keep the truck parked inside; turned into a measure 8 times and buy once scenario. Jealous of
