I got a 400 lay flat positioned over rear axle of swb transit,I will try take some pics.its only the t260 85hp one, barely even notice it in the back,I just took it out to put some furniture in,so will take some pics when my battery on camera is charged.I was looking today how much space a upright one would save,But was thinking they would be very difficult to secure safely with the high centre of gravity?
