The tow bar is the Roadmaster Nighthawk model, however the base plate units mounted to my Jeep are Blue Ox. I had the setup professionally installed at Dan's Hitch in Elkhart when I bought my PC in 2019, and that is the combination they quoted me when I called them to arrange the installation appointment. I don't know why they chose to use that combination of two manufacturer's products, but I have seen this combination advertised in other product ads, so it's not that unusual. I didn't think to ask them what advantage the combination might offer over all Roadmaster components, but I do know that Dan's Hitch came highly recommended, and my personal experience with them is that they do quality work.
The only issue with the Blue Ox combo, as I said, is that since they use 1/2-inch diameter tow pins rather than 5/8-inch pins in the Roadmaster base plates, the selection of locking pins is much slimmer. Other than that, I have been totally satisfied with the tow setup overall. I'm currently on the road with my new pin set from Blue Ox using the padlocks to retain the pins, and it's working great. My only recommendation is to stay away from using those "swivel-lock" type pins shown in my first photo.
