Most of the SP, FP and ACE campgrounds I've been to have potable water on the way in, so I'm not sure why you would travel any distance with a full f/w tank, it's just unnecessary weight to carry. I have bottled water, a 1 gallon bottle next to the toilet and maybe 1/6 tank on board.
My rig does not have a freshwater fill, just a siphon tube that serves dual purpose to fill the tanks, of add the pink stuff, depending on how the valves are set. If I travel over 1/2 full it will spill out the overflow.
Also I would never cap off the overflow for fear of bursting the f/w tank, even a valve is just one more thing to have to remember.
I always travel with a full fresh tank. I want my water to be from a known chlorinated source vs. an unknown source at the CG. My tank takes at least 20 minutes to fill. I do not want to waste that amount of time searching for the faucet then filling the tank at the CG. The whole process can be very inconvenient. The weight of water has no measurable effect on my MPG's.
If your tank starts to drain after being 1/2 full you need to add valves as others mentioned. Yes it is one more thing to remember. But being able to travel with only 1/2 full tanks is unacceptable to me.
Understand the reasons for travelling with full tanks. In my case, a full tank of fresh water would add a little over 600 pounds. For me, that would put me well over my trailer GVWR, so I always plan ahead and fill only when needed and as close to the site as possible.
