We work a 2-2-3 12 hour rotating schedule. Staggered start times from 0430 - 1230, and we have a minimum of 13 trucks on the road during the day, dropping to 8 trucks for a 4 hour period overnight. This covers a rural/urban county that's a little over 900 square miles.
Outlying counties (all rural) are covered by almost entirely 24/48 trucks. One station that runs 48/96, and a smattering of 12 hour trucks to round out the bunch.
Just as an aside, I don't think my company is some exceptionally well-run place, so I'm not sure the CAMTS accreditation really matters. The company I worked for before I moved here to Texas was, in many ways, managed better and they were not CAMTS accredited.
