Thanks to everyone who posted replies regarding my plans to trade in the Jeep and buy a 4runner. One more question regarding the 4 wheel drive systems. Is the 4 wd system full-time, or does it have to be disengaged on dry pavement? From what I have read, the 4wd systems are different on the 4.0 and 4.7 engines. What is the difference? Is one preferable over the other when it comes to trail riding and serious 4 wheeling? Thanks again for the input!
