There is no better or worse answer to the question of whether to choose the trunk or platform as the loading surface for the reacha. Both have different advantages.TrunkThe trunk creates storage space underneath the frame. When disassembled, the trunk holds the individual parts of the reacha together by folding the trunk around it and closing it with the Velcro fasteners.The trunk weighs less (1040g) than the platform (2960g). The trunk can be extended to the full width of the reacha, but the corners are not closed, so small parts should not be transported loose in the trunk as they could fall out.PlatformThe platform is a stable surface for transporting heavier objects with smaller dimensions than surfboards, e.g. beer crates, dog crates, etc. The platform has recesses for fastening objects with lashing straps or expanders, and can be fitted with side walls to turn it into a transport crate so that even small items do not fall out. Even with the platform, the reacha remains width-adjustable so that narrow objects such as a SUP can still be transported upright on the left and right. The platform is made of special wood, so-called CDF (Compact Density Fibreboard) and is therefore suitable for outdoor use, i.e. it can withstand wind and weather.
