I know this is a Toyota section, and you seem more interested in the 4runner than anything else based on your rankings, but I've got to say that MPG-wise the 4runner is nowhere near what the outback 3.6R and other crossovers offer.
Govt ratings show there is a big difference: https://www.fueleconomy.gov/feg/Find.do?action=sbs&id=36859&id=36435
The best mpg I've ever gotten with my 4runner is 23mpg; that was all highway, going 60mph, no head wind and no hills. The norm for the 4runner on highways and rural roads with speeds over 65mph is 21-22mpg. Mixed Driving is 19mpg. City is normally 17-18mpg. You throw in any sort of weight, hills, stop-and-go, cold weather and the mpg goes down from there...for frame of reference I was regularly getting 15-16mpg in city driving during this past winter. This engine/transmission combo just isn't known for its fuel economy.
I'm not trying to talk you out of the 4runner; it's a great, reliable vehicle. But if your top priority is mpg, you're picking the wrong one. Also if you think the outback's rear end is "floaty" on the highway, you're going to be in for a rude awakening with the 4runner's suspension. It drives like a truck and has body roll; certain options like KDSS might mitigate that, but its still a Body on Frame truck and will drive as such.
And you don't need to get a premium trim for the sunroof. While they are not standard, they do come on most vehicles, regardless if its a premium version or not.
In all honesty, a crossover, like the outback or pilot, will likely work for you just fine. You should have no problems going down forest service roads and even getting through some technical terrain, if you drive carefully. If you were planning on tackling hard trails and remote areas for vehicle exploration and/or remote access, I would wholeheartedly recommend the 4runner...but it does seem like an overkill for your intended use and will definitely be a step down in terms of mpg.
Good comment. Crossover is definitely the best play here. Our Outback gets 34MPG highway. In-law's MDX gets close to 30.
By the way, I own a new F150 2.7L. Great truck. Again, overkill for what you're looking for.
