If you look carefully in this picture provided by RedD you can see that seating arrangements for the front and rear of the vehicle is different. In the front, like in the real vehicle, it can hold 4 in the cab. In the rear it holds 16. Previous to OFP:DR in ARMA and OFP1 both front and back where filled in order by who entered first.
This finding looks interesting as it may lead to the moddablity of different ‘transport zones‘. With this I presume you could zone left/right side of a ship, or “Cargo, front, back ” of a large plane. Perhaps this could be even exstended to zoning drop pods in a giant mech, rather then say “Hop in back” – you could say “Hop in Pod1″. Regardless of sheer arcade nature of that picture, I think this is worth while noting as this opens a few doors and at the very least gets the mind going about the possibilities of OFP:DR.
