Most parking garages have 7-8 ft clearance limits, plus tight U turns, I have parked in one before in Houston at the Texas medical center in my crew cab Ford F250 (I live 150 miles from there, my wife had an appointment and I needed to pick up something that weighed over 1,000 pounds for work), it was a chore, involving backing and cutting to manage the turn radius on some of the switch backs, and skipping lots of empty spaces until I found an empty longer corner space. A sprinter based class B is 3-4 feet longer than and 2-3 ft taller than my F250.
HappyWanderer I had a similar experience at the Cosmosphere space museum in Hutchinson KS, I called ahead to ask about RV parking, the girl that answered the phone said the nearest was several blocks away. I happened to arrive on a Sunday, the museum is located at the corner of a community college, next to the stadium, things were mostly abandoned being a Sunday, so I thought might as well do a drive by. Right out in front of the main entrance there is a sign RV/Bus parking across the street.
