A passthrough window is essential if you're traveling with pets or if you want access to your cab when you're inside your camper. The sliding 13”x13” opening makes it easy to pass small items through between your camper and cab. The passthrough window replaces the stock Plexiglass window and offers the same amount of visibility through your camper. 

Note: The placement of this window is in the same position on all campers. Visibility may change depending on truck model. This option cannot be retrofitted to completed campers.
