One suggestion would be to change the pinion on the motor and drop it down a tooth or two or try going to a crawler motor that has more torque for pulling but not as fast as the stock motor.

This is the trailer I'm running at the moment which it is a normal Tamiya trailer.



I have never had any problems with my last trucks of towing this trailer sometimes it has A-trailer in front of it.
