I have the following in my van.
2 Milwaukee 18v cordless drills
1 makita 12V cordless impact (this is my screww gun)
1 Milwaukee corded sawzall
1 Ryobi 18v cordless sawzall
1 Ryobi cordless circular saw
1 Makita corded circular saw
1 milwaukee corded right angle drill (prewires)
1 milwaukee corded hammer drill (can't live without it)
My next drill is going to be the milwaukee 18v close quarter drill. This thing looks awesome for tight spots.
I also just bought a dewalt 12" double bevel mitre saw, and table. (This doesn't stay in my van though)
Oh yeah, and I have an air compressor that stays in my van. It's just a little pancake compressor. Love it for blowing jetline through conduit.
I carry a brad nailer, and staple gun just in case.
No wonder I have no room in my van.
I have tried leaving stuff behind, but everytime I do, I end up needing it..
