same tires, but the tacoma weighed in at nearly 8000lbs loaded. she's a pig. it probably did better because of all that weight on their generally narrow tires. sinking down through the muck to the hardpack
Probably that it is a manual, supercharged, and regeared.
But it's splitting hairs. I'd rather have the made in Japan 4Runner than Usa Tacoma that's built at a lower price bracket.
