I like GCs, have owned several of them, and still own 3; 2001/2002/2004. If you don't need 4-Low, the AWD Toyota Highlanders have quite a bit of room and get over 20 mpg. The downside being that Toyotas bring a premium price. A used Nissan Pathfinder or Xterra might also be a good choice. I'm looking at an Xterra for my daughter.

Pick up a copy of the latest Popular Mechanics. They have a spread about the current crop of crossover vehicles. They say the Highlander fills a hole that isn't there. Toyota makes several others, like the 4-runner and RAV4 that do about everything better than the Highlander.
The article also gives a brief comparison that's worth reading. These are the so called crossovers, though, not the true off road vehicles, so it might not give any useful info for FC's original question.
