I have a small and growing collection of 18v Ryobi cordless tools, drill, impact driver, circular saw, saws all, vacuum, flash lights, etc. Since I am converting to solar I also bought the DC "In Vehicle" charger.
I have a set of electronics tools. Tester. Butane soldering iron and torch. Wire cutters, strippers and crimps.
There is the standard collection of screw drivers, sockets and wrenches.
For leather working I have what I need to make or mend just about thing I need.
In terms of shovels and rakes and implements of destruction I have a shovel and an axe and a hatchet, and a saw, etc. I also have a 14 inch gas powered chainsaw I'm planning to bring.
Lots of people find the collapsable ladders handy but I'm a big buy so I bought one of those modular folding jobs. 7 foot folding ladder or 13 feet extended. That'll get me on my roof.
Things I think I'm gonna need?
Heavy duty tow straps
vehicle specific tools
oil and other fluids changing materials
heavy duty ramps
heavy duty jack
air compressor strong enough to fill the tires on my E450 duelly
10,000 pound winch
I'm certain as the build progresses and I learn more about my vehicle my list will grow.
