I read through many threads on here on the subject, but can't find a definitive answer. Is there a specific brand and size hitch you'd recommend for the Prius (2008 Touring)? It will likely only be used for a bike rack, with no more than 2 bikes on it. Also, is there a particular brand/model of bike rack that seems to be best for the Prius, as far as ground clearance and overall fit? Any recommendations would help, as I have a new bike & am itching to ride somewhere other than my neighborhood!
