We are looking to upgrade from our 2007 Sienna with a 2012-2014 Odyssey, Sienna or Highlander. I find that most Odysseys do not come with a tow prep package, while many of the Siennas do. Interested to hear from Odyssey owners about whether you had to have the tow prep installed at the dealer, and whether you like towing with the Odyssey. We also are considering a Highlander (but they can be harder to find), which we hope would enable us to tow a light-weight high wall or hybrid down the road. If you own any of these, please feel free to chime in on pros and cons. Thanks!
