I'm not sure if there are any laws against it but I'm pretty sure it voids any warranty on the vehicle AND if he should get into an accident he could have some very serious liability issues when it's discovered he was negligent in towing outside of the manufacturer's recommended limits.
You said it right "Recommended" limits. NOT lawful limits. Since he is not breaking a law. Gross negligence will be hard to prove. As for the warranty. Who is going to tell them.
Remember. The manufacturer weight limits are only there to tell you what the manufacturer will warranty the vehicle to carry / tow with out breaking down.. Nothing legal about them.
