I also don't see any strain on my charging system (gauge stays consistent around 14v w/the comps running). I had over 6yrs of daily trouble-free use on my last Thomas comp on my 68 swb.
I can see the York if you have a huge demand for air but for simple stuff I don't get why the electric pumps get such a bad rep.

I'm not familiar with the Thomas compressors. My 480's sticker says that they have a 20amp draw each. I had a 60amp alternator and a single, albeit large battery. (I've since moved up to a dual battery setup with an isolator and a 120amp alternator). I could drive around for a couple days on a full charge and then I'd have problems with a dead battery or the valves acting funny. My system would also show around 14v the whole time. I'm no electrician but I think the compressors were still drawing more amperage than my alternator could keep up with even though it was charging at 14v. Maybe I had a pansy alternator...
Still, waiting 3-4 minutes (10 minutes in my case) to be able to air up and drive really sucked. I went to leave a show a couple weeks ago and a small crowd had gathered to see it lift and I had to sit there for what seemed like a year.
I run pretty low everywhere so I'm always having to air up for railroad tracks, driveways, sharp turns, squirrels, etc. 10-20 second recovery is awesome!
One other advantage that hasn't been mentioned is the York is nearly silent compared to the electric compressors.
