REI of Medford had their quarterly garage sale this past Saturday morning so I stood out in the cold rain for 2 hours to see what they had on sale. I ended up with an as new Yakima RocketBox Pro 12 for about 70% off Amazon's new price. This cargo box is a little smaller than the RocketBox Pro 14 that I was hoping to find but the price was too good to pass up.
I have added two photos of the cargo box installed on Our Journey's sport rack in my photo album. There is plenty of clearance all around. The cargo box doesn't come close to center of the rack so there's plenty of room on the port side for a kayak, solar panel or bike rack. The RocketBox Pro 14 would have also fit just fine with plenty of room to spare.
It has been noted on the Amazon reviews that the Pro 12 can lift up at the forward lip at high speeds. Since Our Journey can hit a max speed of 65 mph on I-5, I have drilled a small hole through the front lip flange of the cargo box and am using a releasable tie wrap to snug everything down - just in case.
The RocketBox Pro 12 looks a bit more matronly than the sleeker long nosed cargo boxes but from the side step I can reach every square inch of the inside. And, it doesn't cover up the roof hatches! Now to load it up with the light but bulky fenders, spare life jackets and such!
