One little thing I cannot stand is there is no driver control for interior lighting. There should be a way for the driver to control the lights from the cockpit. My kids love to press buttons and I usually dont find out they have turned on the interior lights in the back until we are all strapped in. You have to enter the cabin to turn off the back lights.
Radio Controls, Gas mileage, Ride, Interior space. I purchased a 5x30 Ft. acrylic bathtub at LOWE's in the Box and it fit in the back of my Sienna with room to spare!!
