although i personally DON'T LIKE any of the major carrier's, the best pieces of advice i can give you is, instead of trucking, go to "plumbing school", or "carpentry school", or "HVAC school".......
those trades will PAY MORE and will be a nearly forever lasting career move....with (nearly) no lay-off's or slowdowns.....
ok, however, you wish to drive a truck (god, another one wants to ruin his life, and i gotta save him), so this being said, go with swift, and get-er-done.....
next, above all else, just expect to take some crap here and there while you learn in school and on the road.
next, if driving EAST of the Mississippi, be sure to be in ANY truckstop BEFORE 6:00PM.......or you ain't getting in....
if driving WEST of the Mississippi, then "usually" you can get a parking space anytime........but.......don't hold me to that either.........
more of life's advice in the wonderful world of trucking, in the hours, and days to come........
P.S.
someday you WILL BE DRIVING in the Northeast (my area), like NY, NJ, CT, and the rest of New England......
don't be affraid.........we won't bite you......at least, not at first..............;)
