Hey brother I’m one of the first people to think of that idea. Only the car version though because the truck version was already thought of. Actually, I live out of my car a lot and that’s the only place to put a tent.
Sehr kreativ und durch-Dach-t. (Wortspiel in deutscher Sprache mit "Dach" darinnen). - Very creative and through-roof-t. (Word play in German with "roof" inside).
Rooftop tents suck...too hard to put your drunk wife to bed and the late night pee missions are way too difficult....just not practical to need a ladder to get in and out of your tent
