We tow a small camper with our Tracker. It has an empty weight of 780 lb, and with all the gear it is probably close to 1k.
It tows very well with no sway problems, even in strong crosswinds. Unless you have trailer brakes, you have to allow extra stopping space, acceleration is not really good, it struggles on steep hills, but at speed on the flats it does OK.
It doesn't seem to have adversely affected reliability or caused undue wear and tear.
The wiring was a bit difficult to get at. The wires in the harness are small, and I couldn't find a plug-in adapter, so I had to use the fold-over taps. All the wiring you need to get at is in the driver side rear quarter. You will need one of the electronic adapters for the brake/ turn signal lights (about $12 at Auto Zone).
You should be able to tow one snowmobile with no problem, just watch how you balance it. Too much or too little tongue weight and you will have sway problems. You want about 10% of the trailer weight on the tongue.
Good luck!
