Judging from the number of posts, this load-acceptance topic is popular. I'd like to add one point; namely, there are numerous variables in the expediting industry. The load acceptance strategy that works for one expediter, may not work for another.
If you run team, you'll run some loads solo drivers don't.
If you run solo, you'll generally run a higher number of loads than team drivers do.
If your truck is lift-gate equipped, you'll run loads non-lift-gate trucks don't.
If your truck is reefer-equipped, you'll run loads non-reefer trucks don't.
If you're with a carrier that hauls a lot of automotive freight, you'll pick up and deliver to more automotive locations (with their freight cycles and pay rates) than if you were with a carrier that runs less automotive freight.
If the truck driver(s) have a security clearance, you'll run loads that non-cleared drivers don't.
If your carrier has a national reach, you'll run loads that regional carriers do not service.
Even with the same carrier, if you run loads west, where freight centers are further apart, the economics will be different than if you run east, where the freight centers are closer together.
If you carry equipment for doing inside pickups and deliveries (pallat jack, hand truck, furniture dollies, etc.), you'll run loads that trucks without that equipment do not run.
If your carrier lands a dedicated run and your truck is dedicated to that run for a period of time, you'll run only that freight and no other in that period.
If your straight truck has a 24' box, you'll run some freight that trucks with 22' and 14' boxes will never see.
If your back door is larger than that of most other trucks, you'll run some freight that smaller-door trucks will never see.
There is no single load acceptance, truck-equipment, or driver-credentails strategy that is better than another. If the 24-foot dry-box D-unit were the best, you would not have some 14-foot C-unit reefers making more money because they are eligible to haul more high-value and high-paying freight. If C-unit reefers were the best, you would not have 22-foot dry boxes out performing them because the dry boxes have smarter and harder-working drivers in the dry-box trucks.
If configuring your truck to haul the greatest amount of freight per load was the best strategy, B, C and D-units would fade away and E-units would be all we would see. But we dont' see just E-units, do we?
There is no single best strategy. There is only the strategy that works best for the particular driver or team in the truck. Some folks are happy in a basic truck. Others want something more full-featured.
As long as drivers can meet the financial and personal goals they set for themselves, and can keep their carrier and customers happy while doing it, it's all good.
Needless to say, profitability is required for any strategy to work. Keeping the profitability consideration in mind, I think it's great that people with a wide variety of goals and interests can find their place in the expediting industry and the way that works best for them.
