My most recent new tool box is 2800 sq ft, has a 6" concrete floor, 200 amp service, tons of outlets, several welder outlets, a 10'x 10' and 12'x 12' OHD, full bath, 15'x22' office w/ ceramic tile floor, fully insulated and steel lined ceiling. Now that's a tool box!

and yes, I even have a couple of roller cabinets. No....I didn't get it at Sears.
