A few dealers and CourtesyParts WERE selling them for around $126 a while back. Sounds like someone screwed up the pricing back then because now it seems like everyone (including courtesy) is selling them for the (much) higher price. Those of us who got the $126 deal were lucky i guess - and to think I was complaining about the shipping charge!
If you are finding different prices, make sure the difference is not due to one of them including the $55 harness, and the other not.
A lot of people here get hitches from U-Haul. That should be much cheaper - closer to the $130 if they have 'em for the 05 yet.
