Dual hitch receiver

Dual tow hitch for carrying bikes.
Has anyone used the dual hitch for the van and then add in the Reece hitch bike rack… or is it better to have a bike rack in the draw bar
Best part I think is if I disconnect the caravan I still have the bikes on the car
Get a hitch carrier mounted on the caravan, when you take the van off move the bike carrier to the car.
Thanks Smitty, good idea , not sure how that could work on the drawbar, I have a Yakima 4 bike Reece rack (only use it for two bikes though) have been looking for photos of how it would work
