GM's adopted the "no-camo" rule for Camaro prototypes, but it seems as if Ford may have adopted a similar policy when it comes to the secretive F-150 Raptor program. New photos and details at PickupTruck.com gives more insight into the company's off-road program.

Someone with sharp eyes and loads of patience caught this particular Raptor mule as it left Ford's Dearborn test facility. As this prototype wears older F-150 sheetmetal (and not that of the 2009 model), it's likely not the same prototype previously photographed, but a host of features are shared between the two. We're seeing the same ride height, wheel size and fender flares between this and the previous prototype. We're betting the fully-disguised truck wears the 2009 front styling cues, but it's anyone's guess until the camo comes off.

Perhaps the only attempt at disguising what this truck really is comes by way of several stickers scattered across the rear of the truck. Sporting logos for Bilstein shocks, Eibach suspensions and even Petersen's 4Wheel and Off-Road Magazine, it's as if someone tried to make the Raptor appear to be a privately-owned and modified F-150.

However, the lack of any license plate and the giant red engine-kill button on the dashboard suggest otherwise, confirming it is an OEM prototype. That's good news for those of you interested in the Raptor. One prototype may suggest a one-off toy built by bored engineers, but two? That may be sign of an official vehicle program.
