I started driving hay trucks around the field as soon as I was tall enough to see out of the windshield with my feet on the pedals. About 8-9yo. Tractors long before that. Too little to throw 80lb bales around so I got to drive. Drove my first semi at 11. Some friends own a farm in Rosalia, WA that grows wheat and barley for Dry Fly Distilling these days and we were out at the farm visiting. He says jump in, we're heading out, so I hop in his truck and off we go, just the two of us. Dropped me off at this huge truck full of grain several miles from the house and before I could say anything, he shouted "meet you at the silos" and took off in a hurry. I don't think anyone has ever had
that much faith in me since. I eventually figured it out and didn't destroy the gearbox.
Sorry for the sidetrack...I don't need or want trailer assist, as cool as it is
