Expectations for Towing with Toyota Highlander XLE AWD

In my view, no matter what you get (other than a low profile basic pop up), you lack the motor to comfortably cruise except on flat terrain.

When it comes to towing, horsepower and displacement is still king.

No point in running 'the bags off' your Toyota. Get something sized for it. That way, you can take the stuff you want to along without fear of destroying your vehicle from overloading. Your excursions will be much more enjoyable.
