Never seen that. But I used to have a 450#+ semi driver that used an a-frame ladder to get in and out of his cabover International. Literally.
He would pull this 6' orange ladder out across his lap and make it happen.
Jack was an amazing human. Very loving to everyone he ever met.
I've never met a nicer man.
It was very cool knowing he loved driving semi so much to pull a ladder across his lap and out the door to get in an out.
Safe? No. But never a safety incident at all!! And never a complaint at all.
Miss you, Jack Marshall!!
