I don't know if anyone ever made a Class III. I have a Dalan Class II that I believe is rated at 3500 #. I've pulled my car tailer and Vette (5000+ #) and it works but the short wheelbase VX and the long trailer didn't feel real comfortable. I don't think I would recommend it. Be real carefull! I have a small utility trailer, just used it yesterday, maybe 750+/- # and that tows just beautiful.
