I contacted CURT about the clearance from the center of the hitch pin hole to the edge of the rear bumper with the CURT hitch # 12093 on a 2011 Mazda CX-7. CURT was unable to provide this measurement.
However, we have installed another model hitch on a 2010 Mazda CX-7. The CURT hitch should mount approximately the same location as the Draw-Tite Trailer Hitch # 36419. The measurement from the center of the hitch pin hole to the edge of the rear bumper is 9 inches on the # 36419 hitch.... view full answer...
The 20x59 Curt Cargo Carrier # C18151 weighs about 57lbs when empty. This fits 2" receivers and has a weight capacity of 500lbs. If you are looking for a lightweight option then perhaps the 19x60 Curt Cargo Carrier for 2" Hitches - Aluminum - Folding - 500 lbs # C18100 would suit your needs. This is aluminum and only weighs about 29 lbs but still has a 500lb weight capacity. I attached a couple demonstration videos for you. view full answer...
