DH puts major miles on his car for work- like 50k+ a year. He has a Yukon now, loves the size, but it seems lately we're shelling out $1000 every other month to fix it. He's toying with getting something new. We need a Yukon/Tahoe sized SUV that can handle a lot of miles and give us very few maintenance problems. We've heard a lot of good things about Toyotas...anyone have suggestions?
