Well, lets see...
Dad had us boys learning to backup hay wagons without knockin' down the barn as soon as we where old enough to hold the wheel and reach all the pedals.
Older brother went into big rig driving while I was just 13 or so - I rode along during summers and was moving trucks around the yard and loading construction equipment with him before I ever got regular driver's license. He probably taught me the most about real world highway driving with a trailer / load.
Uncle Sam gave me more training and a license to drive everything they had on wheels (plus a few tracks) by the time I was 21.
I managed the staging area of our motorpool during that littel adventure in Somalia. Equipment, truck and trailer parking with space at a premium. I had to park 'em so close you couldn't walk between em. The 88Mike's hated me when they had to retrieve stuff I had parked. Also logged 10K miles of transport driving (trusty ole M818 and anything the unit needed moved).
Since I got a "regular job" 18 years ago, big trucks, trailers and all that are just part of a days work.
Principles of the tasks are all similar between all that and draggin' a big TT down the road, but I actually find I'm a bit more comfortable in a tractor trailer than I am dragging the TT -- just something different in the "feel" sitting down lower to ground, I guess....
