InAlaska,

I'm guessing you've got just under a 1,000 Lbs to give before adding, you, your spouse, pets, toys, fuel, food, etc. and are over by 1 Lbs on dry tongue weight.

If you are planning to travel short distances over flat terrain you'll probably get away with it til it's time to trade for a new vehicle.

You are definitely testing the limits of what nature expects from your Highlander.

See if the dealer will let you "test tow", then you can see for yourself.
