If for no other reason, the 30 amp plug is a much more reliable connection than a standard wall plug. 15a, 30a, 50a is all 120V, just a matter of wiring and the cost difference between running a new 15a line or a new 30a line is minimal.
Careful here. The 50a outlet is a 240v outlet. Most RVs just use the legs separately giving them 120v on each leg. But to label it as a 120v outlet is misleading. The 50a outlet is wired EXACTLY like your 4 pin 240v dryer outlet and uses a ganged 240v breaker.
