I have two Trx300fws with winches. One has a 3000# mounted on the serial number plate and the other has a HF 2000# mounted on the frame behind the serial # plate. Be aware that a winch can easily over drive the stock battery and possibly ruin it. My Wife's 95 has the 3000 but will only be used in an emergency but my 97 with the HF 2000 gets all the log dragging, front end loader, snow plow abuse but mine has a garden tractor battery in the storage compartment under the seat to handle the current. As far as airflow I'd advise putting a fan on any Trx300fw unless you ride at higher speeds with a light load with a clean engine. My choice is an ebay Honda PC800 fan. Mine is manual control, my wife has a thermostat mounted on the engine mount under the tank. She has a double pole switch to allow automatic or manual operation.
