Refrigerator truck

Occasionally, refrigerated trailers have been used as temporary morgues,[1] and second-hand refrigerated trailers are frequently sold for use in tiny home conversions due to their insulation and existing status as a vehicle.

[citation needed] The first successful mechanically refrigerated trucks were made for the ice cream industry in 1925.

[2] American inventor Frederick McKinley Jones is known to be the first person to invent a refrigerated truck.

[4] They are often equipped with small "vent doors" at the rear and front of the trailer.

These doors are kept open while hauling non-refrigerated cargo (often "backhaul") to air out the trailer.
