I feel like the desire often expressed to make every single-level car a Viewliners is really just rail fan fantasy, by those who want to gawk at a nice and shiny uniform consist. The way I see it, there aren't many logical reasons why all (any) new coaches and lounges should be built on a carbody that was originally designed for sleepers, and that would need to be assembled by a new manufacturer and on a new production line. CAF's production of the V-II has been a disaster in pretty much every way, and though the cars are here now, they are probably the least likely manufacturer to consider building more Viewliners for Amtrak. The tooling and assembly lines will be gone, and gone with it any reason why the V-IIs would be the best platform for the single-level fleet. If CAF were willing to build more cars (which they're not), there would be something to be said for utilizing the pre-existing production lines and tooling. But since CAF is pretty much done with Amtrak altogether, a completely new manufacturer would be required to take up production of the new Viewliners, which would negate any possible advantage of having the tooling and infrastructure in place to build the cars. Just the way I see it.
