All electric no propane needed
At the Tampa RV supershow last week a motor home salesman stated they have a model that is all electric. No propane tanks....nothing runs on propane......I did not think to ask about 12 volt lights e...

Some of the new high-end all-electric coaches are actually listed at 100 amps . . .
Not precisely; 50A service is 50A 240V split phase service, the same power as a 50A household service entrance would have. You can't successfully connect a single 120V 100A electrical device to it--though, of course, there's nothing on an RV that meets that description, so it's perhaps a bit academic. I understand the "100A" coaches typically have two 50A 240V split phase inlets.
The main confusion seems to come from specifying amperage apart from voltage. Perhaps it would be better to rate the various connections as as 3.6 kVA (120V 30A service), 12 kVA (120/240V 50A service), and 24 kVA (120/240V 100A service).
Similar considerations come up when combining batteries in the DC system. Two 200 Ah 6V batteries are wired together to make a 200 Ah 12V battery (if put in series) or a 400 Ah 6V battery (if put in parallel). The energy storage ability of a battery cannot be expressed solely in Ah without the corresponding working voltage; Both of these setups can supply a theoretical 2.4 kWh of energy.
