Alternator Identification

I have a 2005 Bigfoot Class C on a E450 cutaway chassis with a 6.0 Powerstroke. Does anyone know how to identify which alternator I have (without pulling it)? There's a sticker on the driver's door that specifically says it is NOT equipped as an ambulance. I tried the Ford Etis site with my VIN, and it just tells me the model and engine, nothing more. I'm putting a lot of new electrical stuff on the coach side (solar, inverter/charger, lithium batteries) and one item is a DC->DC charger to charge the coach batteries while driving, so I need to know what the alternator amperage is. Pulling the alternator, or doing most anything on an E450 is a special kind of hell. On the VIN decoder I found here, shows mine as having a 130A on the Equipment tab, and on the Specs tab, it says:
Maximum Alternator Capacity (amps) 220, 130 130.0 min 220.0 max
Which means?? Is there some way of testing it, short of removing it, to tell its amperage? Or some visual ID? (if I can get a mirror in there close enough and my old eyes can focus enough to read it). From my inspection it looks like the Ford 110A, or the Bosch 140A, definitely not the L-N 230A. Thanks in advance....
