Inline 6. Only decent engine offered. Poor gas mileage, top heavy and prone to tip. Electrical demons galore. Not nearly as roomy or as comfortable as others of equal size.
No inline 6 since 2004. I get 17-18 mpg on local commutes and 20-21 on the highway. That's a solid 4-5 mpg improvement over my old Explorer and Blazer and it's more comfortable, handles better and is more stable on the road than either by a long shot. Mine has 78,000 miles on it so far and no problems beyond normal maintenance. WAAAY better than that piece-o-shyt Blazer ever was.
