I just picked up a Rola Hitch Mounted Cargo Box for my MDX. It has 13 cubic feet of storage space. It also has a swing away frame so I can open the hatch without any restrictions from the box. We drove 140 miles back home and saw no reduction in gas mileage. I bought it on eBay for $250

Since I didn't have roof rails and with all the problems finding a cargo box that fits the MDX I thought this was a great alternative.

 

Dang, that's pretty nice. It makes me retink getting roof rails and weathertech racksack.

 

Looks good!

I can see that being very handy in low parking garages and/or height challenged MDX owners. I like how it swings out to open the rear hatch. How hard is it for one person to put it on/off?

 

When the box is removed from the tray it can be installed by one person. If the box is mounted to the tray it requires two people.

 

That's an AMAZING deal - is there any way those sell for that price anywhere regularly? I'd want one in a heartbeat - any link to the auction (or I'm guessing it was a one-off?)

 

No, that was a lucky find on ebay. I had to drive a couple of hours to pick it up but it was worth it. The best price I found on a new one was $679.
