The Jeeps and the Honda CRVs are probably the two most popular toads. Everyone has their own opinion, but you might consider the Jeep Wrangler if you have enough tow capability to pull it. A stock Wrangler Sport 2dr weighs in around 3700 and a 4dr is around 4200 lbs. I've pulled two different ones now for over 20,000 miles combined with no problems whatsoever.
They are very easy to hook up for towing. Attach the tow bar, transfer case in neutral, transmission in park, braking system set and you are ready to go (unlock steering on 2007 and older).
Just a suggestion, if you get a Jeep that is 2008 or newer, you don't have to leave the key in the ignition when you tow. My previous tow was a 2005 Wrangler and you have to leave the key turned to the first notch to unlock the steering. The newer Jeeps use a microchip in the key fob as theft deterrent instead of the locking steering wheel.
Just my $0.02 worth, others will vary.
