So I recently built a set of drawers for my 4runner. Came out WAY better than I expected. Lo g story the same length, I stumbled upon this, RTT. I am now planning on building my own. Mine will be the same foot print as the tepui kukeman. That way I can use the rain fly, and travel cover, that can be purchased from tepuii. A rough estimate on cost puts me at about $500. That includes tent material, ladder and hardware from tepui, wood, rain fly, travel cover. And should be fun. I have access to an expert seamstress with top notch equipment (momma), so altering an old tent, or making a new one from purchased material, is no huge deal.
