30 amp is 30 amp. 50 amp is two legs of fifty amps and a common ground not 100 amps total.
30 amp service gives the RV owner a total of 30 amp to use (OK less but let's not get hung up on details). A 50 amp coach gives the RV owner a total of 100 amps to use (split between 2 separate circuits). That's a HUGE difference.
If someone was actually looking at a 100 amp coach that would be 4 50 amp circuits but some would likely be setup to provide a 240V circuit for certain appliances. This is not typical in most RV's.
