With abf they came to our apartment in raleigh, and then dropped the trailer off in Pa at our house when we moved. We didnt have to go to a terminal. That was a few years ago, so things might have changed.
The way it worked three plus years ago, they dropped the trailer(s) at point A for three days then at point B for three adys. At that time they would store the trailer(s) in one of their yards as needed on a monthly basis. I think it was 395/month which is not bad.
The situation was that I had to close on the house we were selling then buy the next one so I had already planned on a month's storage fee. We were down to the wire and I was dickering back and forth on a couple of properties. The place we settled on is a bit off the "beaten path" so to speak. It happened to be outside of ABF's service area.
This situation never occurred to me and I found out about it at the last minute. Anyway, I dealt with it. I went ahead and used ABF then rented a Penske truck and shuttled my "stuff" from the terminal to my house.
Oh', I had three pup trailers so it took me like seven trips plus one wasted trip. With most LTL's like ABF, only the largest terminals are manned 24/7. The smaller ones lock up but the line haul drivers have keys.
I had made arrangements for a trailer to be left outside of the gate on a Saturday which it was. Then, a line haul driver rolled in, saw the trailer, figured someone had screwed up and put it inside the fence. So, I show up, no one around, don't know when the next line hauler will roll in so I bagged it and went home empty.
This is not a diss on ABF. They provide a very reasonable alternative for the DIY person. Quite a bit less than say PODS.
