I still recall the couple parked next to me one year in Las Vegas
They flew in and the dealer picked 'em up at the airport, drove them to the lot and handed them the keys to a brand new class C. Gave them the tour and off they drove..... They parked next to me. Sticker in the window.. He has a few memory issues and was having problems figuring out the door lock, having the same model door latch (Tri-mark) I showed him which key fit.
Well, they decided to visit Sam's Town for dinner
The parking structure did have enough clearance for the rig but... that pipe that warns you you might be too tall hangs down a bit lower than the height marked upon it
It came in under the Winegard TravelStar TV antenna, tore it off the roof, bounced up and came down on top of the bathroom vent smashing it to pieces.
Still had the sticker in the window they did.
