The V6 will have better mpg, it just won't have better performance. Rent a 4Runner for a weekend trip and see if you like it
Honestly at this point I am sold on the 4runner. I LOVE my Jeep TJ Rubicon...gonna break my heart to sell it, I literally just put a new stereo system, LED lights, on top of a BRAND NEW custom built tranny, and I have full skids, sliders, Warn 9.5ti never used, fancy bumpers, the list goes ON and ON and ON....BUT at around 90k miles its like I had to throw all kinds of money at it, just lots of minor stuff but enough that it is a pain in the rear. My girlfriend jokes she has PTSD from the amount of time my Jeep has to go to the shop, and my neighbors always ask "do you need to borrow a car? is the Jeep running?" I mean its a 2005 and its MINT, and I am anal retentive on upkeep, and when I spend money I buy the high grade whatever it is and go to the top mechanics the Jeep clubs say to use, etc....I have pampered this TJ but as a DD its a nightmare. To hear that brand new GC can have quirks, no way, forget it. I just cannot deal with that, and the Jeep dealers in my area are AWFUL. I mean AWFUL. I had a warranty TSB issue that is a half hour job, one dealer kept it for 3 days and just reflashed the computer, the next dealer kept it over a week and then tried to do all kinds of extra work on it I did not ask for. I even mentioned it to my girlfriend today that lots of guys say the GC has to go in for service a lot potentially, and she was like "with the dealers around here that would be bad!"
I do not know what else I would really want at this point. Any other SUV is going to be too big for my needs and parking space. I would not mind a single cab short bed Chevy Silverado, as I owned Chevy/GM 4x4s all my life and they've always treated me GREAT even when I beat on them hard. Heck I bought my dad a 2004 Silverado 4x4, only things I did was put a leveling kit on it, got the engine and tranny custom tuned, an exhaust, rims, toolbox, floor mounted gun rack (key for my old man and me doing lots of shooting and hunting when I am home)....he now has 210k miles on it and still drives it daily to work 45 minutes each way with NEVER any major work. Its needed new exhausts (but in Pittsburgh the salt chews them up in no time), wheel bearings, and a u-joint. That is IT. BUT if I get a single cab short bed pickup its kind of useless with the girlfriend and her kids, or if I have family, etc. Basically a 3 seater. But I do love the power of a V8 and the cab room as I am a big guy. Which makes the Tacoma not appealing as the interior seems small, and I liked the old ones better than the new ones (and have read the new ones have quirks).
I need a reliable DD, and in my daydreams something that can trail ride if I get the time, as well go camping and hunting when I have the time....and the other daydream is whatever I buy new now I would want to be able to modify and wheel harder once it gets older and the warranty runs out. The 4runners seem to have such a plethora of aftermarket accessories, reliability, and fanatical following so lots of you guys to get help from IF there are issues and IF I ever do want to build one up.
