Over the holidays my wife and I drove the Armada to see all of our family as we had 10 days off from work. We drove nearly 1000 miles with a combination of driving - hwy and city - but mostly hwy. Just before we left I installed the MegaWarrior. I was happy to see we avg 16.5 mpg and let me say that I was moving 75-85 mph +
on the hwy the whole time. I'm sure I could hit the 18mpg just cruise controlling it at 65mph. I was afraid the big rack would obliterate the mileage.
I had a smaller rack on the Armada before and I always got 16.5 on this type of trip with the smaller rack. Plus I've been averaging 14.5 around town with either rack. I had the smaller rack from day one so I assume that I would probably get a little better mileage with no rack but I wouldn't own an SUV without a rack... I just like the look and extra storage. Nevertheless, like I said I was thinking that the MegaWarrior might just kill the mileage and was glad to see that this wasn't the case.
I had a liberty before and before that an Excursion. So I went BIG and then small and now JUST RIGHT in terms of size. Anywho, I only got 17.5 in the Liberty on this type of trip. (had the small rack on the liberty).
I really think the gas mileage on the Armada is outstanding considering its size and power. Plus as gas prices rise I feel like we won't see an overabundance of Armadas on the road or other full size SUVS for that matter. So I figure I spend an extra 45.00 - $65.00 in gas a month over a "mid size" SUV and that is a small price to pay for the comfort, safety, space, prestige and overall lack of seeing a million other Armadas.
JMO of course.
