Looking for SUV recommendation

There are a lot of small SUVs rated for about 5,000 pounds towing. I would stay away from most of them. They are unibody which means no actual frame. Some may not allow the use of a weight distributing hitch which you will need. They are not really meant for regular towing, their rating is largely just a marketing tool.
I would look at a Tahoe or Suburban from GM or an Expedition from Ford. A Durango might be good too but I've never like Chrysler automatic transmissions.
