SUV like tahoe but better mpg?

I used to have a 2004 Subaru Forester and loved it but it was too small so I had to get something bigger and a traded it for a 2000 Tahoe Lt. I like the size and horse power but the mpg is killing me at about 13. What other SUVs or pick ups would be around that size because I need bigger than the Subaru but I need better gas mileage. I also still need to have 4wd and have good ground clearance. I would get a newer 4runner but they are so expensive. Thanks in advance!
