Dont loan out your tools

When my F150 went down and I still had some towing to do, I borrowed a friend's F250 with a worked 6.0L. I treated his truck better than he did.

I told him if he breaks it, that's on him. If I break it then that's on me and I don't have the money to fix it.
You were indeed lucky. My buddy that I loaned all the tools to works almost exclusively on 6.0 , 6.4 , and 6.7 Ford diesels. He has 4 lifts and at any time two of them will have Ford 250,350 cabs in the air, working on those POS diesels. He'll have 20 -30 Ford Diesels at his shop at any given time. I would never borrow one, cause like you if it broke on me I would be responsible.
