Should I bring tools with me?

I carry a pretty good craftsmen set, it comes in handy quite a bit, just this Friday as I got on to 10 headed in to Jax an oring on my PTO lever(I pull end dump) blew out, causing an air line, behind the dash that controls the raise and lower function of the trailer, to also blow out. By the time our mechanic showed up an hour later I had it buttoned back up and was putting the dash back together, I try my best to fix it if I can, I’ll call it in and get someone headed my way, but if my shop can talk me through it and save some time, I’m all about breaking out the tools.
