Tailgate Hitch Bbq Smoker/grill

I've been trying to look for van or truck accessories that can be used for camping. I found these tailgate grill hitch






What are your thoughts on this compact grill? Anyone here who owned something like that? Seems a good way to cook the foods during camping or weekend trips.

 

That smoker is as big as that jeep

 

Looks like you could be cooking en-route, and have your meal ready on arrival.
