Yeah, its a 1st gen (88) Ranger SC with the wheel base shortened to 108". Side note, anyone thinking of shortening the wheel base on their ranger, 108" is only 1" longer than a two door explorer sport so you can use the stock rear drive shaft off one if you are running the D35/8.8 combo.
All those pics were taken at Rausch Creek Offroad Park in Joliet, PA. The trail in the last three pics is called "Yellow Jacket" and I think it is rated as either blue or black (can't remember which one but it is definitely 'black' when covered in ice!). For those that don't know RC, the rating goes green, blue, blue-black, black, red in order of difficulty.
