I did the same thing Evie, under a stone archway in a park for the locks on the Columbia River last year on the third day after I picked up my rig in AZ. Busted the satellite dish, scraped all the seals on the sides and eventually had to replace half the ceiling!! It was marked for height and I even passed the chain guide that hung down before it but turns out it was not the same height for a rig as wide as mine!! Even had to go back thru it as there was no other way out! I stay away from all such things now...:)
Glad to have such fine company lol. Saw someone last week take out a bunch of pumps in Q, didn't we Kerry?
