Hello, Lightning. Teacel has given you some good info in his response. I'm currently running at 27% Deadhead, due to the luck factor, but my average is 34% this year. I consider three types of deadhead in my calculations:
a) Deadhead to Layover
b) Deadhead to Pickup
c) Deadhead to inservice or to go home.
It can get very expensive in dollars, time and mileage on the truck, to have to drive over a hundred miles to a layover point, only to be given an offer that requires over a hundred miles or so to the pickup, especially if this happens often. Learning how to handle this requires a little time and experience as you learn where the best areas are for freight. As to whether or not we will take a trip, we consider if the total miles offered will pay at least a dollar a mile. It is a good criteria for us and has worked well so far. Doesn't mean we will absolutely refuse a little less, if the run will put us in an area we want to be in for better runs. Get the picture?
Being concerned with deadhead is the mark of an expediter who is serious about being successful. It is one of the first big issues you discover when starting out in this field, along with your relationship with your mate/co-driver! Some good advice is to talk to other expediters when in a truckstop and see what works for them. Also, agree with your co-driver that you won't take a run unless you both want agree on it. Helps relieve the stress that deadheading brings to a team. Keep up the good work.
