For me, it was the rear hatch lock extension. Using this gizmo, when 
camping, to prop open the hatch slightly, as well as having a front 
window or the pop-top screen open, introduces fresh air into the van, 
keeping the interior's temperature well below that of an iron ore 
smelter. Having the ability to lock the hatch in this position provides 
a moderate level of security as well.
