Merkava.

[Imp]

4 seats per side. Another section in the same site says that the layout of the Namer APC troop compartment and that of the Merkava is almost identicle

I would say the pictures dont tie in with this, Merk very cramped though incredibly roomy for a tank due to shoehorning the engine in the front.
Namer is a limo most spacious APC ever? nice well spaced seating & decent headroom.
How is simple crew & electronics take up a lot less space & the Namer if anything offers a bigger profile as the superstructure runs the full length & is around half turret height.
