yes mader is a working wrecker, matter of fact these pics were taken shortly after unhooking from a E-350. i still use the sling a good bit and used it on the E-350 earlier that day. i use the wheel lift, sling, and towbar. we tow anything from compact cars to bobtail semi's with mader so depending on the tow we can hookup to anything. plus i like to say .....real men tow with slings!!! lol
