A day in the life of a feeder driver may consist of starting in the mid afternoon, finding a trailer, possibly having to clean it out, (pallets from the day before, sweep it out). Then going to a customer location and picking up anywhere from a couple of pallets, to a full trailer load, to just switching trailers on the door at the customer location. If you only picked up a couple of pallets, you may stop at 2 or 3 customers, with a couple pallets here, a couple there, etc. You may or may not have to load the pallets with a pallet jack. Usually the customer loads with forklift. Then you return to the hub, drop the trailer, maybe repeat with another trailer, maybe play yard jockey with a switcher or your tractor. Then after lunch you may run to the railyard, another hub, or possibly more customer pickups.
Or you can have a job, where you take a load to one hub, the a: go back to the first hub and repeat, b: go to another hub, the return to the first, or c: go from point a to b and back. Or you could be yard jockey all nite.
The good thing about feeders in comparison to other trucking jobs, 95% of the work is drop an hook, 5% is when you have to clean out or load at customers. You get to sleep in your own bed every day. You usually work at nite when there are less idiots on the road.
The bad thing, you usually work at nite when there are less idiots on the road.
