Roadmaster Tow Defender that Fits Flat Towing Setup with Blue Ox and Demco Components

Question:

I have a Thor class A motorhome. It has a receiver added to tow a Honda Fit. We sold the Honda Fit and now have a Honda Civic. A Blue Ox baseplate is being installed, but we will use the same Demco tow bars with adaptors for the Blue Ox baseplate. I was looking at the Tow Defender to protect the Civic while towing. What dimensions are needed to make sure I am ordering the right one ? I would prefer to install it under the tow bars and wiring, but not actually necessary. Your thoughts ? Thanks,
