Any shipping manager will tell you that no two shipments are alike. 

A shipment of bubble wrap will not be treated the same as a shipment of heavy construction equipment which in turn will not be treated the same as a shipment of cellphone parts. Nor should they be treated the same.

Every shipment deserves its own setup and every shipper knows, choosing the right mode of transportation is the first step to shipping any freight. And if the mode of choice happens to be LTL or TL, this is the article for you.

Luckily, even though no two shipments are alike, the number of different trailer types is limited.

The top 8 most common trailer types:

  1. Standard Dry Van
  2. Straight Truck-Bobtail
  3. Pup-Trailer
  4. Reefer-Refrigerated 
  5. Flat Bed
  6. Step-Deck
  7. Conestoga
  8. Lowboy Flatbed

All Specs: The same as Dry Van and Pup-Trailer

The dimensions given vary for all configurations of the Dry Vans, Straight Trucks, and Pup-Trailers

5. Flatbed

7. Conestoga

A hybrid between a Dry Van and a Flatbed. Built on a frame sharing the same dimensions as the Flatbed or Step-Deck, the vinyl walls and/or roof are retractable allowing cargo to be loaded from the side or top. The cargo will stay protected from the elements during transit.
