Fuel a heavy-haul load where the truck is
A jeep, tractor, and trailer on a permit clock do not peel off for a retail island. The distributor has to meet the load.

What the filter is checking
Turn on heavy-haul fueling when that is the job. The list keeps published distributors who marked that capability, sell the fuel, and cover the ZIP. Wet hose and after-hours add quality points on those searches because they are how a night move actually gets fueled.
The flag is the company’s claim that they fuel this kind of work. It is not a promise that they will fuel every unit on the deck. If the transformers or the excavator on the trailer also need fuel, write that in the notes.
Give them the pin and the hour
The ZIP is where the truck will sit, which may be a layover, a port ramp, or a job entrance rather than the next city on the permit. Gallons are for the power unit unless you say otherwise. The hour is the permit window, not the hour you hope to be done driving.
State pages describe the corridors that change the trip: mountain grades, port gates, and city curfews. Use them for context, then rank the ZIP so a distant yard does not outrank a wagon that covers the pin.
Questions
Does heavy haul mean they haul the freight too?
No. It means they say they can fuel heavy-haul loads and jobsites. The carrier is still your truck.
Can a featured company sit at number one for this?
No. Featured listings appear in a labeled strip and are left out of the numbered rank.
