You want to try backing into the Winnipeg post office when it was down town, designed for 48’ trailers and have to put a 53 in there on the second floor of the building. Ya the 2 nd floor. Only had 10 minutes to do it or you had to shut off truck and wait for exhaust fans to clear air. You say no prob but the posties wanted it exactly square with the dock or they wouldn’t unload you. For a guy that was just learning it was a nightmare that’s where I learned to back up lol
