Specifically what pictures are we talking about? The very first post of this thread has photos showing identifying characteristics of a Sienna with the towing preparation package for a Sienna with the 2GR-FE (3.5L) engine, which is used starting in 2007. No 2006 Sienna engine - with or without the towing package - will look quite like this because a 2006 has the entirely different 3MZ-FE (3.3L) engine. The 2006 towing preparation package does not involve engine changes.g35zuniga said:I have a 2006 AWD limited, according to the brochure and some discussions here, I have the tow package as standard equipment. Based on the first pictures however my sienna doesn't look anything like what is shown. Do i for sure have the package?
