Every commodity has its own number, and one trailer only holds one
Food is not a temperature, it is a list of them. Frozen product runs at 0°F or below, and ice cream, novelties and frozen dough run colder still.

Produce, frozen, protein, dairy and beverage each move on their own numbers: a precooled trailer, a pulp reading written on the bill of lading, a box whose prior loads you can name, and a delivery that lands inside the appointment window. Dobie coordinates food freight across the 50 states and through the South Texas crossings, with every carrier verified the day the truck is assigned.
In short
Two clocks run at once. One is temperature, and every commodity has its own number, so produce, frozen and fresh protein do not share a trailer. The other is shelf life, which started in the field or on the line and keeps burning while the truck waits at a scale, a crossing or a closed dock. Food also carries a sanitation record that no other freight carries: your receiver can ask what that trailer hauled before your load, when it was last washed, and what the reefer logged the whole way. Any one of those answers can stop the freight at the door with the seal still on.

The numbers
Who this is for
The process
What the product is, how it is packed (bushel cartons, reusable plastic containers, gaylords, slip sheets, floor loaded), pallet count and weight, set point and run mode, the precool you want on the trailer, whether wash-out and prior-cargo documentation has to be produced, and what your receiver requires at the door in appointment time and remaining shelf life. Those answers decide which carriers can even be offered the load.
Active operating authority, current insurance with limits that match the commodity value, and equipment that fits the assignment: single temp or multi temp, able to run continuous for respiring product, fuel on the unit for a border or receiver wait, and a trailer that can document its wash and its prior cargo. Certificates are verified the day the truck is assigned, not once a year.
Trailer pulled to set point before the doors open and the unit shut off during loading. Pulp readings taken on pallets from across the load and written on the bill of lading. Freight loaded off the front bulkhead so return air can reach the evaporator, off the rear doors, and below the ceiling chute so the discharge is not capped. Seal applied and its number recorded on the bill of lading.
Arrival inside the appointment, because a produce receiver refuses a late trailer as fast as a warm one. Seal checked before the doors open, pulp taken at the door, condition documented at both ends, and the reefer download retrieved at delivery so the record exists before anyone needs it. If a receiver refuses a produce load, a federal inspection at destination is ordered while the freight is still on the trailer.
Equipment
The same product line can need cold, a clean dry box and a cross dock in the same week.
Yes. Dobie is based in the Rio Grande Valley and the South Texas crossings are weekly business, including the reefer side of it: fuel on the unit before it stages, continuous air through the wait, and coordination with the customs broker and the Mexico-side carrier so the unit is not switched off at a hand-off.
The one you specify in writing, because you own the commodity spec and the receiver's requirement. What we do is make sure the set point, the run mode and the precool are on the dispatch, and that the carrier assigned can actually run them. If your product is chill-sensitive, say so, since a 34°F trailer ruins bananas, avocados, tomatoes and cucumbers just as surely as a warm one ruins berries.
That requirement goes on the dispatch before a carrier accepts the load, and the record is the wash location, the date and the prior loads in the box. Understand where the requirement comes from: the federal sanitary transportation rule makes prior-cargo and cleaning disclosure mandatory for bulk vehicles, while the last-three-loads standard on a reefer or dry van is your buyer's rule. So confirm on the first call what your quality group or your customer accepts as proof, because that format is set by them and it gets verified against the specific trailer assigned to your lane, not assumed from the equipment type.
Not in a standard reefer, which runs one set point across the whole box. Frozen at 0°F and produce at 34°F need a multi-temp trailer with movable bulkheads and a second evaporator, which costs pallet positions and shrinks the carrier pool sharply. Two single-temp loads is often cheaper and always simpler.
The reefer download is most of the case, read against the pulp readings taken at loading and at the door. That pairing shows where the product warmed and who had it at the time: a rise during a delivery stop points at doors open there, a unit off overnight points somewhere else. On fresh produce, a federal inspection at destination ordered while the freight is still on the trailer is what turns a dispute into a documented claim. The load travels covered by the assigned carrier's cargo insurance, with condition documented at pickup and at delivery.
Because liquid in glass, cans and PET is dense. Bottled water, soda, juice and beer reach the 80,000 pound federal gross limit with pallet positions still open, and canned goods, sugar and flour behave the same way. The load plan is built on pallet weight, count and axle distribution, and filling the last positions is how a legal gross becomes an overweight drive axle at a scale.
Yes. Co-packers and processors move sweeteners, oils, flavors, film, preforms, closures and corrugate inbound on the same schedule discipline as finished cases outbound, and a plant that runs out of closures stops the line as effectively as a plant that runs out of product. Food-contact packaging carries the same trailer sanitation questions as the food itself.
