We looked at a 2nd generation Sequoia recently and the family loved it, but it was in poor condition. I found a different 2008 for a pretty reasonable price and low mileage but it has the 4.7L V8. Does anyone have experience with the 4.7 in the Sequoia? Does it feel under powered? Is fuel economy as bad as the 5.7? Trying to get a feel if it is worth checking out.
