I think it depends on your objective. For right now, I am trying to dampen the noise when driving. The cab can be very noisy depending on the strength and direction of the wind. The results that Art got seem to be pretty promising IMHO. I would also like to get rid of at least some of the bugs on the front bulkhead as well, but that is of less import.
If they pan out, I will then consider putting them on the rear. The objective there will be to firstly reduce the amount of dirt that accumulates on the back. Also to clear the area during rain so my rear view camera is clearer (I use it full time when towing my trailer or car). Secondly, although not that important to me, it would be nice to see some fuel economy improvements.
I'll post once I get them installed and have some experience with them.
