LJAZ - they (2010 models) don't come with any rockguard on the front end. I guess that has been discontinued.
jb_bb - thanks for your input! Interesting point on the resale aspect.
As I thought, we'll see how it goes this year and re-assess based on conversations with people and performance of TV and TT together. There are short flaps on the back of the 4Runner already so I'm hoping we have no problems!
Total newbies to this business so I appreciate the comments
