Bob,
1. If you wear glasses put an extra pair in the truck... Extra shoes and a change of clothes... extra undies for the Hallmark moment you're bound to have.... extra batteries and a charger for whatever cordless stuff you carry.

2. A practical tool belt. You don't want to have to go back to your bag for everything. At the same time you don't want to spend one day a week at the Chiropractor from wearing a 50 pound belt all day.

3. E-Tools for general inspections I wouldn't want to be without.... Greenlee DVC-6.... Good multimeter.... Good carbon monoxide detector.... Tif 8800 or better gas detector .... Protimeter Survey Master.... a good quality cordless drill (some guys prefer a screwdriver)....

4. Re camera choice: as sturdy looking as you can find and make sure it doesn't require anything proprietary. No less than 10X optical zoom. Don't get sucked into the digital zoom number. Make sure it's small enough to carry, but big enough to handle comfortably. I currently use the Kodak Z7590 and like it. I've never needed hi res for a job. USE THE LENS COVER between shots, whatever you buy. I have a 2 gig memory card. They're cheap.

5. An assortment of ladders. A first aid kit.
