Is the installation a permanent one? Can it be easily removed for cleaning of bed of truck, or hauling?

The pack rats are mounted to the bed of the truck or floor of the van. These can be removed if needed. If removed you would need new hardware in order to install again.

Can this box be made with one wide compartment and two standard compartments?

Asked by: Anonymous
The horizontal dividers can be removed to make a larger compartment. You cannot remove the vertical ones, as it is required for support. You may also look at 334-3. At this time the 338-3 is not going to be modified for the larger compartment, like the 334-3.
