not too bring back a thread from teh not-too-distant future, but I finally followed through and got the trailer hitch installed!
I ended up ordering one from ebay, a "Curt" brand Class III 2" hitch for about $150. Appears to be pretty good quality, though admittadly my mian interest isn't for towing its just for mounting the bike rack and some other things, so I'm sure this will be more than good enough.
The install was a little on the "interesting" side, though if I had a buddy to help or a transmission jack or something it probably would've gone a lot easier... most of the work was spent getting the first two bolts in, after that it wasn't too hard. It didn't require any drilling (though the instructions said 05-07 would require drilling to get the bolts through, because they don't have the frame access hole at the rear of the vehicle the newer ones do... mine had it, so it wasn't too hard. It used stock holes in the frame to mount to, and carriage bolts with brackets that you "fish through" the frame so you don't have to get a wrench up on the frame, which would be about impossible anyway. Their method of fishing the bolts is actually pretty neat, I'm sure others have seen it but it was a first for me... a long "fish wire" which at the end was coiled so you could thread the end of the bolt into the wire itself, and then pull it through with the correct end coming out first!

This really saved a lot of time and frustration.
Total time for the install was about 2 hours, though like I said if I'd had a friend to help lift/jack it into place, probably could've had it done in 45-60 minutes, most of that time was spent trying to maneuver it into place.
All in all, not too bad of an install, decent price, and looking forward to using it!
