Got my Isuzu cabover diesel stuck, well not really stuck, just spinning. Had the ASV RC30 in the enclosed trailer behind it, figgered what the heck, got nothin to lose, so I pulled the 3500 lb loader out, ran a chain to the front of the 11-12 K lb load. Dang near stalled the hydro drive out, a coupla times, but it pulled me the 20 feet I needed to get back on the asphalt. Here is a video of a similar machine...
