We finally had some to time take the Rhino on a road trip. Before we left on our trip, we installed our motion windows and maxxair fan (although fan is not running yet). Install was scary cutting holes in a new van but all went good. As for our trip, we drove about 2500 miles to Las Vegas and the Grand Canyon. We threw a mattress in the rear and off we went for a week. We mostly drove I-40 Texas to Nevada and back. Gas mileage in our diesel version was 16.5 on a very windy day and 21.5 on a good day. Highway speed was mostly 70-75. Van was nice to drive but got a little tiresome and squirrely in the wind going 75.
