I'm not really a truck person, so a pickup is a last resort. whatever i get will be a daily driver as well as a tow vehicle. I'll be towing an open trailer with a 2300# car on it.
So far, I've ruled out Mitsubishi Montero Sport and Jeep Liberty.
Any suggestions?

Chevy astro cargo w/4.3lt vortec or C10 full size Chevy van. It's nice to have the extra room of a van when at the track.

Get the Dodge SRT-10 :D ;)

Dodge Magnum wagon.

get a vovlo v70 R and put a hitch on it

Chevy Trailblazer!!! I can hook you up I deal those too!

I would look into getting a Dodge Dakota. It has the class leading towing capicty of 6,600lbs. The 4.7 V8 makes very nice power and it has a lot of torq.

What's your price range?
New Nissan Titan truck is pretty good.

have you looked into a subaru wagon? im sure they make one that can tow that little and still get good gas mileage

Dodge Ram

price range is low 20's at most. 1 or 2 year old low mileage vehicle is a strong possibility as well.
Subies don't tow. Volvo-interesting but too expensive, and i didn't even check the towing capacity. Magnum-i wish. Astro-i must look into that. So far it's looking like an Xterra or Cherokee if i can find one with low miles.
Pickup? Dakota club cab with 4.7, if they've taken care of the ball joint issue.

Astro towing stats:

ASTRO TRAILERING DATA

Maximum trailer weight (lbs./kg)(1) RWD 5400/2449 AWD 5100/2358

A very good used one can be picked up for around $10,000

I noticed you mentioned a cherokee.... those things are BADASS, they can tow a lot, comfortable, 4.0 actually gets decent gas mileage, and it will last FOREVER if you change the oil at normal intervals. I had one for a few months before I got my XD. Jeeps are GREAT. My next car is going to be a Grand Cherokee :D
