I use a custom tool belt that i kind of built around what i choose to carry... In the top pocket i keep all my electrical tools. The middle pocket has a lighter, sockets and bits. The large main pocket has my moisture meter pouch sewn into the one corner that i made for its protection, a power screw driver, mirror, wrench, pliars, and a multi screwdriver. The lowest pocket fits my camera and a couple extra panel screws. My flashlight hangs off the front in an altered hammer holder (i had to smash it together a little, it was too wide) Then i also use a little tape measure pocket that i hooked onto the back side of the main pouch for a tape measure (mostly to keep clients busy if they want it), a telescopic magnet, a torpedo level, a small LED flashlight with a laser, and a service wire guage. I also take a 12' Cosco little giant like ladder into the house for goofy attic hatches. 28" 200 lb rated aluminum extension ladder with self levelers. (now wish i had bought a fiberglass one, this one is bouncy at times)In the car i have a ventilator, knee pads, gloves, rain gear and boots, and...tp. I have a tool bag in the car with a few other random things that i rarely use, and back ups of a bunch of the above stuff. I leave the bag in the car. The only time i ever took it in with me i left it there... i guess i went on a little there...
