Pittston, PA. Salt Lake City, UT. Those two are "full service" terminals. Also have Duke, OK. Denver, CO. I think Miami, FL. And a new one in Portland, OR. Never been to any of those "lesser" terminals myself so can't comment on them.
Typically you will park your trailer at Oak Harbor Freight lines in the Auburn/Kent area. However, there have been times were i have delivered in Portland and parked it at Prime Floral there in Portland. Also they have had me drop my trailer in Kennewick and Bobtail from there rather than DH from Eastern WA with my trailer. I've picked up empties at various location around SeaTac... Even at a Saia truck terminal. Prime Floral has Portland (Wilsonville) OR, Oxnard Ca, Miami FL & Pierson FL. They have loading docks and offices in permanent buildings... Unlike Denver, which is a glorified drop lot with a portable building for offices.
We also have a manned yard in Auburndale, FL. Which is pretty much a gravel lot with a doublewide trailer on it that the guy who runs the yard lives in with his wife. Also, I wouldn't call the Portland/Wilsonville floral yard new. We had it when I started over 4 years ago. That being said, I haven't been to it since I got my own truck, over 4 years ago.
I didn't call it new, however they have built a new trailer pad for empties...longer no longer have to worry about tearing up the grass on the hill with the ICC bumper... With the new lockbox you don't have to hike to the office for kingpin locks.
I've seen Prime reefer trailers parked at two Knight terminals: the terminal in Dallas, and the terminal in Fontana.
