GMC S15
I have an '86 C22 with a single axle Trailrite trailer that I tow behind a 1984 GMC S15 extended cab 4X4 with a 2.8L V-6 and 5-speed manual. To be honest it's more than I should tow with this small an engine. It's O.K. between home and the ramp because I don't have far to go nor any long hills. The trailer, with a spare tire hanging on it, weighs the better part of 1,000 lbs. I weighed everything once when I trailered it to Port Albernie, Vancouver Isl., British Columbia, Canada. The boat by itself, loaded down with two and a half weeks of provisions, hit 3,200 lbs. so the boat and trailer was about 4,200 lbs. Way more than should be attempted with a 2.8L V-6! That's with a Class 3(?) hitch, of course. I drove semi for several years and I didn't feel real comfortable with it. With a 4.3L S10 for local towing you would want to drive conservatively and keep your foot "out of the pump" when pulling hills so you don't build too much heat in the engine. Otherwise I wouldn't think you would have a problem, as long as you drive sensibly.
