Anyone use a laser measure to measure height or clearance?

Mostly interstates until we get close to home and where we store it, those will be the only concern on the way home.

I'm aware of the tail swing, heard it mentioned on RV forums all around. I wonder every time I read it why it's so prevalant...I pulled at 38 foot gooseneck horse trailer for years and never noticed 'tailswing' enough to feel like it was an issue. Maybe I was lucky lol. I do wonder if it's less prevalent on a horse trailer where the axels are set further back than on a 5th wheel camper.
