I saw a megacab ram around the other day and it had me thinking about how much room there is behind that door. I mean if ram added another 4" to the cab you could have a half door like the extended cab pickups and get another row of seats for when you need it*.
I doubt it happens, but if it did I bet they could still sell it even if it had a 4' bed. I wouldn’t even be surprised if it happened.
*You don’t need it. Even if you have 7 kids you don’t need it, just get a van (and maybe wrap it up once in a while)
Edit: I should have been more clear. I know there are custom ones out there already, I was just thinking if we’d ever see these from the OEMs
