Jon, that is a very rational observation of thought. The subject came up on here a few years ago and their are folks interested in them. Since cost of starting out with them is relatively the same as running a set of duals, we are starting to see many tour and over the road buses running them. I have heard gains from Prevost fleet owners of a 6-8% savings on fuel, but like you said it may not pay off for the guy that don't run the miles.
I noticed at the last Nascar race I attended there were at least three racers running them on their Prevost conversions and those were all slide units. I believe they are very stable running 20 ply's. They could be a tad stiffer, but with air suspension you are not going to know. One driver had told me he felt it to be a more tuned ride. I was thinking I posted a picture on here with them installed on a newer Prevost. We will have to compare the load capacities and see if that is currently any kind of issue.
