From the F150, Ford has scaled down the length of the Explorer.  It's at 5320 mm versus the F150's 5702 mm. (A Civic is only 4450 mm long- measure your garage before buying a Sport Trac!).   Thankfully, they took out the length from the pickup bed and not the cabin.   The cabin seats four adults comfortably, five in a pinch, with adequate legroom and headroom front and rear.   All seats are leather-covered, too, for a very unpickup-like cabin.

The cockpit feels like vintage 90s Ford spiced up with modern touches.  There's a smattering of silver trim around the center console, dashboard and door grips.  Gauges are white-faced and large enough to read, but sadly the odometer and trip meter are still mechanical, as is the gear indicator.  Clumsy column-mounted shifter frees up some cupholder space, but that could have been put to better use by a front center seat.  Window switches still look the same as those on a 1980s Taurus, but are finally improving in feel.  Front seats are wide and supportive, yet soft enough to be comfortable for city driving.

For those excited by the Tonka look of the exterior, there's no shortage of toys inside the cabin either.  There's an overhead compass-thermometer, CD, a power rear window that opens up to the pickup bed, and aircon vents and controls for front and rear.  The audio system is also of a dual nature, with separate-source headphone jacks for the rear; the kids can listen to their Pokemon CD while mom and dad listen to the impeachment trial on AM radio.

White-faced gauge cluster comprehensive but ruined by mechanical odometer and gear indicator.

Interior is  roomy...which isn't surprising. There are luxury intentions inside such as beige dash, sliver linings and leather seats, but nothing hides the fact that this is truck-based. 
Dual aircons are common, yes.  But dual sound system?  Rear passengers can plug in their headphones and choose their own sounds. Eat your heart our, Mercedes-Benz...
