Slip In Units

Slip in units are great for saving the interior of your pickup box from wear and tear.  This style of body can be urethane insulated making it a popular option for hauling produce and other temperature sensitive goods.  Insulated bodies are lined with plastic kemlite over 1/4" fir plywood.  Plastic kemlite lined bodies can be washed out with pressure washers and withstand moisture very well.  The general construction, options, and features of these slip in units is the same as our toppers.  Aluminum framing and skin keeps the weight low and body life long.
