These very convenient ABS 3.5" walls provide structure when you want to use the KARGA as a box. This means immediate access to your groceries, plants, pickleball gear or whatever, in the same place as when you got in the car.
The sides do not include the whole KARGA, but the kit does come with four sides, eight stakes to hold it in, and four corner columns/extrusions for support.
These walls can be added to a single or double level KARGA.
