The Ford F-150 shown is an Atlas model that has been modified with Herpa semi-truck wheels, Athearn truck running gear and florist wire to make the nerf bars and crash bars . The other is a Herpa Jeep Grand Cherokee that Michael scratchbuilt the running gear; the wheels are from an Ertl Dodge Ram pickup that look right at home here and the nerf and the crash bars are made with the same material as the Ford.
