This Youtuber's channel has him doing practical mechanical repairs to old equipment. He has fixed his several light trucks, two half-tracks, a forklift, several Jeeps (mostly CJ2s) and lately a part-military part-civilian 1 1/2-ton short wheelbase 4x4. This video caught my attention because he is working on straight-six 1950s GMC engines. There are a number of situations that arise which make a fellow laugh at his jokes and what he says about acceptable standards, and also muse at the practical mistakes he is avoiding.
