6'
The 6' units are for use in Compact, Mid-Size, or Full-Size truck beds with a minimum bed-length requirement of 6'. This unit is most popular for pipeline work, where storage of other tools in a larger truck bed is desired.

8'
The 8′ units give the technician the most room inside possible for them to work. They also have the most storage inside of the unit. For plant/ shop work, this unit is the most versatile mobile darkroom.

8' Generator
Identical to the 8' unit above, with the addition of a storage compartment on the drivers side for generator storage. This unit is versatile as it allows you to have the interior space of an 8′ unit with the ability to equip your own power supply.
