What vehicles have the towing capacity of 3500kg

have to know the maker of vehicle

this information is in the glove box owners book

light weight or heavy duty towbar
will be on tag on tow bar fitted to vehicle

rarely see anything over 1800 kg at tow ball

you will have two tow weights capacities

unbreaked trailer and braked trailer

Depends were you are, where I live any trailer with a ladened weight over 750 kgs requires brakes. Then when you do have brakes you are allowed to tow a trailer up to 1.5 times the weight of the tow vehicle.

You will need to contact Toyota to confirm but I think the tow weight is 1500kgs MAX.

A Toyota Tundra can pull the space shuttle but stopping on a down grade is a different story. Towing capacities are base upon stability and pulling and stopping but should never exceed the cars weight. unless electric trailer brakes are used . but again if trailer would jack knife it will push your car into a tree without stopping because weight has overtaken control.

Depending on the gear ratio of your vehicle you have a max capacity of 8,500 or 9,500lbs. Your ideal trailer weight for this vehicle I would say is between 5,000 and 8000lbs. For more info on towing Click here.

Tow capacity for that vehicle is about 10.000 lbs (adjusted for wear and age). This number reflects max tow capacity with good tires (proper rating and good condition) with all suspension components in good used condition. The capacity of your tow hitch must also match your load and assumes proper trailer weight distribution and tongue weight.
For best results, I also recommend that you use a good quality synthetic gear lube in the differential and synthetic fluid in the transmission, as well as a trans cooler if not so equipped.

With a 20 year old vehicle, the original towing capacity does not apply.
I'd set a limit of whatever the weight of your vehicle is as a safe number (if car weighs 3,200 lbs, tow weight is 3,200lbs Max.) Trailer weight is also determined by the capacity of the hitch.
Trailer loading should be at 60% of weight on hitch.
Don't forget...you need a fully functional cooling system, adequate (most times additional) transmission cooling, and good suspension (air shocks, variable load rear springs and fresh differential lube). If this is done, you may be able to add 20-30% more trailer weight.
One item often overlooked is that it really does not matter if you can pull a load...you need to be able to stop it. Make sure your brakes are in really good condition!!!

Towing capacity for any vehicle depends on the engine size along with tire size. the towing capacity should be on the ID tag on the driver's side door and will also be in the owner's manual.
