I also emailed QuickPitch about flat pack shipping and had the same experience as you. As guess they are only interested in the Australian market. I went back and forth on how to setup the cargo area and was planning on going with the Maltec setup above. My wife shot it down because of our kids......go figure! So I've decided to do what Expeditions 7 did with their Troopy. I've already got it partially built. Just need to source some slides, etc., which is not easy to do in Japan. By the way, you mentioned that the wheel arches are from the GRJ71. Do you a part number?
