Can a Chevy s10 tow a bass boat on a trailer?

If I were you, I would check the towing capacity by checking that by vin#.

Only if it is really light. How much does it weigh? Does it have trailer brakes?

If the boat and trailer combo weigh more than 5200 lbs, then no. Most bass boats are extremely light and with the trailer usually weigh in around 3500 lbs, so no sweat whatsoever - as long as it's the 4.3 V6.

I have almost 250k on my 2004 ZR5 and pulled a 19ft deep v hull with no problems.
