I've got a similar WH.
You're fine to run it on 30A, but like dougrainer wrote, you're going to pop the breaker on the 30 Power receptacle if you run almost any other high power item ( A/C, Microwave ) at the same time.
If it really bugs you, you can get an RV Energy Management System that will monitor how much power you're using and trim the load by removing power from specific items when the load goes above a certain point.
I have on in my coach and when I'm on 30A service, if I have the A/C and the water heater on, if I turn on the Microwave the EMS automatically cuts power to the water heater. When the Microwave goes off, it returns power to the WH.
The one I have isn't made any more, but here's a similar thing - http://www.intellitec.com/index.php/products/Energy_Management/Smart_energy_management_systems/Automatic_energy_select_switch
