Good idea. Nothing quite so important as driver comfort. The legroom number given for 60 series in post above is incorrect. It's significantly less than 42 inches. I would think that the interior size difference with the US Land Cruiser wagons could be stated with this inequality: 200>100>80>60>55.seat design and cockpit design arent really reflected in those stats either. the wheel position in a 62 isnt optimal for a tall driver, etc.
just back to back drive them.
