Here is a topper we just finished for a customer. This is an aluminum topper with a ladder rack, a bed slide style tray for storage, LED interior lighting, and aluminum storage shelves in the sides with organizer bins. This unit will definitely be nice to work out of!
A view from the rear with the doors open.
The pull out drawer unit is a Weatherguard PackRat. This drawer unit is built to fill full of tools or supplies and to haul things on top too.
These are the organizer bins. Anyone of these can be remove as simply as lifting one out. The shelves that hold the trays are extruded aluminum for light weight yet strong support.
Thanks for looking!
