New tow vehicle for my tent trailer - we aren't truck people

My '08 Highlander has towed cargo and travel trailers for over 140,000 of its 170,000 miles. I use it for work and play. No big problems other than a bout of fluid leaks a year ago, and those problems stopped when I switched from the stealerships to an honest independent garage. I just might shoot for 300k miles with this Toyota, it's too good to get rid of.
