I've often done things like detach a trailer in a sloped driveway, rotate it 180 degrees, then try to get 4 dudes to push it up. Sorry if this was the wrong place - I figured "tow and haul" was "place where people do real work with their truck" and this is "real work - pushing cars out of ditches, moving trailers, not getting your bumper crushed with the work truck in front of you backs up, etc etc".
