I go to 2 different multi-story parking garages at the Hospital Campus
One garage has a 6" painted Plastic pipe on 2 light weight chains.
I pulled up to it & i did not move the plastic pipe, so i drove very slowly up a few levels up to the roof & there was no scraping noises.
The other garage has that plastic pipe at 6 foot, but the pipes that run along the roofline look much higher.
So I measured the highest point on my Ram & then the Security Guard took my tape measure & remeasured the high spot on my Ram & walked into the building & measured several places & told me that there was plenty of room.
He did it for me, because every time i looked up, i had a dizzy feeling, that is one of the reasons that i go to the hospital
My Ram has the 20" wheels & the coils have the additional 1" ride height
Then i have another 4 or 5 " for my sign brackets
