L.A.-based ICON 4 X 4 specializes in building retro off-roaders beefed up with modern performance. For this 60s-era Power Wagon, they take a brand new Dodge truck, either a 2500 or 3500 MegaCab, and fit the old body over the top for a ride that drives like new—with a 5.7-liter Hemi—but looks like an off-road weapon from the past.
