I learned most of what I know in the Army. Working as a generator mechanic it was both gas & diesel engines plus electrical. And when I joined we also did hydraulic stuff. So I learned a wide range of stuff.
Then thru the years I got to work on a wide range of equipment that wasn't part of my initial training. From dirt bikes to the fast attack buggies because they had a VW engine. And then a lot of other unique stuff that you'd only see in certain parts of the country.
I'm no fabricator by any measure.
That is a lot of cool, varied experience. Obviously, some of it was not easy by any means, but still cool from someone has never had the experience to do any of that unless I go out of my way to try to do it. And don't that often.
And tangentially related to the jeep.
Fwiw I'd 100% call you a fabricator lol I couldn't do 1/2 this stuff you do.
