I ordered a Draw-tite receiver and aftermarket wiring from Etrailer.com and was quite happy with the experience. I put up a few pics of the receiver on cardomain for you to check it out.

I doesn't really stick out that far but with the spare tire above it any extra length is a bonus. Haven't bumped it yet with my shin.
Anyways the breakdown from etrailer was as follows:
75128 Hitch Receiver $131.57
18382 T-One Wiring Harness $32.70
Shipping UPS $15.64
I ordered it late Monday night, they shipped from their Missouri warehouse on Tuesday, and I got it on Thursday. Very quick.
Anyways, with my package I received a "Platinum Club Card" which has a discount code on it for a 5% discount. If you decide to use etrailer try this code and you may get the 5% off which I didn't get to use:
XJJB7. It's just a business card with the code on it so you and anyone else feel free to use it, hey 5% is at least a free beer! I would think this code can be used by anyone until the expiration date on it of 12/31.
