16,000 miles, 4 years later the velcro appears to be as good as ever. I haven't tracked miles on dirt roads.

We've averaged 9 camping trips annually, normally weekends, with a few of longer duration. Based on this usaged, I estimate about 4 miles per trip on dirt roads. Some places are paved all the way while others are not so this average is a swag. Figure maybe (9 trips x 4 miles x 4 years) 140+ total miles over dirt. We've never experienced any extraordinary dirst or dust except for a tire blowout a little over a year ago.

We drove about a 1/2 a mile to get off an overpass and changed the tire. There was a bunch of black rubber dust on the top shell area which would rest next to the tire when the TM is closed.
