You may need to pay attention as to what electrical items you have on at one time (with the water heater electric element) if you have a 30 amp RV. It's also explained in the link above.
P.S. it doesn't sound like the person conducting this PDI was at all familiar with the operation of a Suburban water heater. He may need to read the link too.

Thanks very much for this - clears things right up. Sorry I didn't find it in a search before asking.
I was aware of the danger of turning on the electric heater with no water in the tank but it begs this question; are people emptying their hot water tank between trips? I don't plan on carrying much, if any, fresh water in my fresh water tank but I *though* that once the HW tank was filled, it was going to pretty much stay full unless specifically drained via the anode port or other drain on the tank itself. Sure, I'll drain the HW tank for winterizing but I was assuming it was going to stay full of water until then and the risk of burning out the electric heater was pretty low.
