Interesting, I was in Sedona a few years back and we considered the Pink Jeep tour but elected to just rent one on our own. Basically we did the same trails that they did at 1/3 the cost. It did seem to be very popular in the area but it does seem like a small niche market. As for the Ducks they just had to many accidents and bad publicity. The line between company owned and franchise was always blurry to me.
