We have a 140" wheelbase first generation high roof Sprinter and it just barely fits under our 9ft garage door. We don't have rooftop AC so the antenna sticks up highest - above the fantastic fan and vents. We have to unscrew the antenna before garaging the unit, but that's way easier than needing offsite storage!
We've rented a 144" (second generation) Sportsmobile Sprinter and the rooftop configuration looked similar, although I didn't have any need to garage that unit or attempt to unscrew the antenna.
