I know lots of people who drive Tacos. While 22 mpg is a bit too optimistic, 20-21 some do get. Alot depends on how and where one drives as well as aftermarket add ons. Something that is usually a mistake.
They are well known for being very capable off road, for holding up and lasting a very long time. That's what makes their resale value so high.
They aren't as capable off road as the Rubicon Jeep, or the Dodge Power Wagon. Their breakover angle isn't as good. And they don't have either the front differential locker or the sway bar disconnect. But they are odviously better than the stock, 4 cly Jeeps I've run for the last 12 yrs. E
