I do appreciate all the advice you've given me on this. @djohnson54 You have a point about not getting too worked up about sound quality - especially in a truck where road noise is going to be a bit more than in a more sealed sedan or coupe. I think I'll invest in a good digital media player - an iPod 6; an Astern; maybe an Onkyo or a Sony - and work on ripping and downloading in ALAC, as @dbtom2 suggested.
the vehicle in question can function as a wifi hotspot, so that's a bonus.
