Can we travel with fresh tank full? We lose half on the way.

"Forget to open or close those valves just one time, and let me know how you made out."

So, I should always have water in my water heater? So, in case I forget to fill it before turning on the electric element, I won't burn out my element?

Gees, I guess I am living a very risky life!

I find it very simple to remember to open my vent valve after I get to my campsite. Just part of the setup process, like chocking my tires, or disconnecting my 7-pin plug before I move the TV. ;)
