Ranger Bands are great. Just use bicycle inner tube and cut them to desired width. Makes for a heavy duty rubber band.
Propane torch. I’d prefer to have an oxygen acetylene set up, but for right now all I have is the little propane stuff, but it does most jobs well.
Good boots. I don’t care what you say, if you have shitty boots you’re having a shitty day. Good boots helps get everything else done.
A quality headlamp. Frees up your hands, always points to where you look, and the headlamps that are available today are top notch (just got myself a new one recently, Black Diamond brand, love it).
A lot of the good stuff has already been mentioned, so I’ll leave it at this for now.
