Question:

1. Other than price, I could not find any difference between Curt 13703 and 13704. 2. I plan to use this for bike racks.What does it mean when the instruction on the 13703 say: WARNING: ALL NON-TRAILER LOADS APPLIED TO THIS PRODUCT MUST BE SUPPORTED BY AUXILIARY STABILIZING STRAPS. The 1304 does not have the same warning. How are AUXILIARY STABILIZING STRAPS secured?

Expert Reply:

The difference between the Curt Adjustable Width Trailer Hitch Receivers # 13703 and # C13704 are a couple things, starting with the # C13704 having a 5,000 lb towing capacity and 500 lb tongue weight capacity while the # 13703 has a a 3,500 lb towing capacity and 350 lb tongue weight capacity.

Both fit box frames, C-channel frames, or I-beam frames, though the # C13704 is for frames 22" to 68-1/2" wide while the # 13703 is for 22" to 72" wide frames.

The Stabilizing Straps # 18050 which are needed for the # 13703 are easily secured; you only need to find a place for the hooks to grasp onto. I have added a link to a video showing how these are used on a passenger car.
