Cargo pants are great! Carry just a little belt pouch for a couple of screwdrivers, plastic conductor guages/wireshovers, backup flashlight and a few other things and the camera bag on the belt at the other side. Everything else fits in the pockets. PDA, moisture meter, IR thermometer, etc.
It’s not perfect but it minimizes getting hung up in the crawlspace and attic.
Levi makes good ones that look like khaki’s with pockets, so you can still look relatively professional. You may not look like a professional banker… but you’ll have deep pockets.
