The Traverse/Acadia is a more apples to apples comparison to the Highlander than the Tahoe/Yukon. Front wheel drive unibody designs give you more interior space, with the downside being the duty level. If interior space is your main consideration, a minivan or crossover are actually better choices. We rely on a Honda Odyssey for the majority of people moving that we do. But, with a family of 6, taking the ATVs somewhere requires towing capacity north of 5K pounds, which is tough to find in a crossover. Most top out around 4K, it seems. Add in things like an integrated brake controller (or at the least, pre-wiring for it), self leveling suspension, and a standard hitch, the choice is clear.
