To add another data point for consideration. Just picked up an adjustable B&W Tow & Stow with up to a 7 inch drop to tow a U-Haul trailer. Setting it at a 6 inch drop meets their ideal hitch height. I’m driving a 23 Bronco Raptor with factory specs - no additional lift, 37 in KO2s, etc.
Yes. The rear crossbar from a 4dr has to have one of its bolt holes expanded to fit on a 2dr. It’s relatively easy with a file. But do know you will most likely need to make this minor modification.
