We have a 2015 Highlander with the 3.5 L, V-6 that will tow my bass boat with zero issues. Been considering going to a newer version, mainly for the safety features that are not on the 2015. I have a concern about the ability of the 4 cylinder to accomplish the towing task and still be a good long-term, no hassle ride. As background, the current ride has 78,000 miles and other than replacing the crappy OEM tires at 35 k miles, and oil and filter changes, this vehicle has not cost me another penny for maintenance. Oh, I forgot about the wiper blades! Finally had to replace the rear wiper blade at 76,000 miles--it just didn't hole up, lol.
