It really boils down to personal preference.  

Are these highway miles?  Suburbans get at a solid 17mpg on highway. 
Durangos get slightly better, but are not as large.

I have found that if you drive mostly highway, MPG shouldn't be as much of
a factor.  Here is what I average - MPG wise on my trips to work on the
various vehicles we have.

2002 Monte Carlo:  29.3mpg
2001 Dodge Durango:  18mpg
2012 Charger:  28.5mpg
2012 Lexus ES-350:  27mpg
2003 Harley - Dyna Wide Glide:  53mpg
