Ill tell ya what, the box nor the tools make the mechanic. A friend of mine was a diesel mechanic for years. Alot of his stuff is older CMan, williams, and various other mixed bag. He also makes specialty tools you would pay 2 arms and a leg for off a truck or even online. Somehow or another he was excellent, he didnt spend big bucks on a box either. Somehow he made alot of money at his job and wasnt in debt to the tool trucks. He only gave it up b/c he got bored of it and hurt his back anyways.
Also: The worsy looking shops Ive ever seen, where tools were all over, tools were quite old and not all truck brand, the mechanic was covered and filthy, the shop was a mess-not only was the mechanic the most honest-but was one of the best mechanics. Ive seen it several times before.. A friends shop is like this, the dealer cant figure out the issue, another mechanic cant figure it out-but somehow his guys can.. Amazing isnt it?
I used to roll with a 26" husky box, full of stanley, older husky, cman, some snap on and mac, matco, etc. Total mixed bag. The guys would always laugh at me and claim I didnt spend on tools. But I didnt owe $$$$ to the tool trucks and got to keep my paycheck every week unlike them.
