We think that Blue Ox and Roadmaster are first class in customer service and support. Roadmaster has many more miscellaneous parts and products and is sold in Camping World. And both make good towbars.
But for the life of me, I cannot see why Roadmaster baseplates are desired over Blue Ox. After we disconnect our toad, we quickly & easily always remove two small round Blue Ox inserts to make our Jeep look 'normal' and not bump our legs when we walk in front of our car. I know Roadmaster baseplate outside parts can be removed, but nowhere near as easy as Blue Ox inserts. And to store the Roadmaster parts is another story as it is big and heavy. Most never remove Roadmaster parts from front of toad and to me, the cars look like toads, shins get bumped by owners and strangers, and towing hookup parts are vulnerable to parking lot damage.
