Dodge Van tow vehicle ??

I have a few years back like 2000, I had a 1/2 t., slant, 833 OD , I would pull a car trailer with a B body on it, and some parts in the bed,.... NO brakes on the trailer, ONLY problem was getting it rolling, once going it went with no problem, even in OD! I always wondered when I would roast the clutch!
