This is a set of two side walls that come with the purchase of a Darche 120 awning. I purchased a new awning, but I will not be using the walls themselves, so I am selling them. They are new and still in the bag. They are for a 120 awning, but they may be adaptable to other awnings with modification. They have mesh windows, so they should provide good ventilation. Please refer to the official Darche website for details. Darche darche ARB Adventure Kings Front Runner Rhino Rack Jimny Hilux Land Cruiser Prado Overlander
