|"Featuring a tailgate and bogie suspension, this trailer will serve you humbly."|
It is equipped with a tailgate that can be opened or closed like the Val's All-Purpose Hauler. Unlike the Small Trailer , the 531 Hauler features 4 wheels, a much larger potential hold capacity and an advanced suspension system. This trailer is the only one that currently features an advanced suspension system. If you look closely, you can see the wheels rotating themselves to an angle perpendicular to the ground, which provides suspension. The 531 Hauler is also the only vehicle that does not have wheels under the bed. This trailer can be spawned for $260 in-game Money , and can appear in many colors, including pink.
It is possible that the name of the trailer is a reference to the user Spacek531, who proposed the idea of the trailer to Defaultio in a tweet. The cost of the trailer in the game is double of the proposed cost.
The 531 Hauler spawner is 24 studs long, 12 studs wide, and 0.2 studs tall. In the past the spawn pad used to be 14 studs wide.
The 531 Hauler itself is 21×11.8×4.4 studs if the tailgate is raised.
The holding area is 14.4×8×2 studs.
The tailgate's length is 2 studs.
