I looked into crossfire products after seeing them on some big rigs and talking to the drivers. They probably do increase tire life by 20%. The problem with that for RVers is that even as a full timer I will probably have around 60,000 miles on my tires when they are 5 or 6 years old, which would be the point I would be replacing them anyway.
I think for commercial applications where they may put 80,000 to 100,000 miles on a set of tires in 8 or 9 months then squeezing an extra 20% out would be worth it. To me spending the money to put the system on an RV would be a waste of money.

I feel the equalization is more important for consistent tire temperatures than extending tire life. If one tire is low, excess pressure is placed on the other and heat causes failure. Lots of directions to go on anything but perfectly inflated tires, but equal pressure/equal temperature is the key. Even wear across both is the second benefit. RV tires will dry rot before you need to replace them based on tire wear. Big Rigs drive over 100,000 miles per year so they get multiple benefits from this. Anything is better than nothing.
