Midsize SUV covers the PPVs (Fortuner, Montero Sport, Everest, Terra, MUX, Trailblazer) and unibody big crossovers (Sorento, Santa Fe, Explorer, CX9, Pilot).
I may not be sure but the Explorer sure looks big inside.
The BK Pajero looks promising space wise being a box and all. I saw it once in a showroom though the 3rd row seems roomy mababa ang seats and seems manipis yun cushion. Roomy but not comfortable I think.
