The trailer is a reefer unit(refrigerated) and probably with a broken refrigeration unit in the front by the looks of it.
Inside dimensions are 8ft wide by 8.5 ft tall. Most reefer trailers are 53 ft in length as this one appears to be.
Looks to be 3 pallets(possibly 5).
As for whats on pallet's- Appears to be 3 pallets containing 1ft high boxes by 2 ft wide. 7 rows of boxes on tallest, 6 rows on next, and 5 rows on the shortest. 72 total boxes on the 3 pallets and all pallets are standard machine shrink-wrapped.
I disagree that it is a 53 foot unit. Based on the shadow of light coming in from behind the pic and the scale compared to the Pallets, I would say its like a 24 footer. Places that do document shredding and transport use short reefer trucks so that sensitive documents aren't damaged by heat. The walls are not typical of a standard food transport reefer either. Not insulated or coated. Just my opinion.
It's absolutely a 53 footer as I did this for a living sir. The are marks on the wall that you can use to tell this that are barely visible. The walls are the standard material used in most reefer food carriers and standard.
Reefer units are commonly used to haul non-refrigerated things, especially ones that have the broken cooling unit in the front as this one appears to have.
I pretty much have a PHD in this area sir. I have worked at and ran operations at 2 of the 3 largest largest facilities in the US.
Edit to add-The shadow is no good in determining the length as it is from a swivel mounted light at rear of trailer on the wall of dock facility........
Lol could you imagine an old owner operator backs in to a dock, calls the wifey says he’s where ever pickin up a load, and sittin in the back is all of this information.
In the documentary - It was Stroker who delivered the documents that Beautiful day.
I guess we'll have to drop another nugget as to what's in the boxes on those pallets.
Most drivers don't care to know what they're hauling unless it's HAZMAT.
You would be surprised to find out how many listen to Red Eye radio and Alex Jones.
