I can see the need for one. My H3 is filled with Ipe, Reed, wife, me, and the associated crap. If we add more either Ipe will need to share the cargo area, or I'll be adding a box (or wining a GOBI - Please! Please! Please! GOBI Gods, I've been good, I promise!
).
I don't know why, but I've always been partial to Yakima equipment.
Maybe its the US vs Sweedish made thing...
