Flooring
Flooring in the trailer is another important consideration. Aluminum flooring tends to result in a trailer that’s lighter, but wood flooring lets you secure loads to the planks and eventually replace the boards when they become worn. Aluminum flooring is also adequate for hauling sand, soft dirt, and gravel, but concrete blocks and debris will require steel flooring, which can increase the cost and weight of the trailer considerably.
Reefer Unit
If you’re looking for a used reefer trailer, pay particular attention to the age of the refrigeration components. Typically, sellers will be able to tell you the number of hours the refrigeration unit has been active. An average trailer of this type can rack up between 1,200 and 1,500 hours per year
