Do you have to travel with SOME water in the fresh tank.. NO,
Can you let it run dry: Yes
What will happen if you do let it run dry: Basically. nothing, in fact as part of the winterizing process, I pumped and sucked mine dry.
Do turn the pump off if it is empty however.
Now.. Why would you want to at least partially fill it..
With water in the tank in a Class A or C should you need to do anything involving water (IE: Make coffee, Get a drink, Dispose of the drink you drank some hours ago) you have water to use or flush with. Pull off the road, do what you gotta do, and continue on your trip.
With a trailer you got to get out and walk around some, but the rest is the same.
Without water in the tanks.. You need to find a rest stop.

The places we camp, I know there is water available right at the dump station before headed up the mountain road. I figure why pay for the water to fill my tank at home, when i can fill up at a place where, essentially, my tax dollars have already payed for it. I live in the high desert in Idaho, and water is not exactly cheap here.
we almost always travel with a full FW tank and always have about 3 gallons of water w/chemicals in the Black tank.
we carry our water because we normally dry camp and i know how good our home water is. plus we do like to use the toilet enroute.
and since we have plenty of extra towing capacity so we don't have to worry about or count every ounce of water or cargo.

I almost keep a full FW tank. One never knows if there is a need for it. The exception is when taking the TT to be stored for a while, then I drain the FW and GW tanks completely. That way, it minimizes algae forming, although it goes without saying that a good sanitize job is needed at the start of a season.
The black tank always has some water (3-5 gallons) and some dish detergent. This keeps the solids from turning to stone.
Living in fire / earthquake / possibly tsunami country, there always exists the possibility that I would need to use my rig as a 'bug out' vehicle, therefore, aside from other preparations, the FW tank is always full, and the black and gray both always have a minimum of a couple of gallons of water sloshing around in them.
We will mostly be camping at the track where they have bathrooms and showers.
I'm afraid of using the water in the 5th wheeler we are getting because I'm not sure where the closest dump station is and the cost. I should probably keep some water in there. Is it bad to keep the water in there for too long as we won't be using it often?
