Empty or full, no difference, never felt slosh either. I keep it full at home so I am ready for the "Big One". If I am going where I have no water I travel full. If I will have water there I travel with about 10 gal or so just for those emergency stops. The FW tank is behind the axle so no added tongue weight and it doesn't remove enough to matter.

I really don't think water sloshes around as much as one might think even with a half empty tank. To me, I don't give it a second thought. I travel with about 1/3rd tank for the toilet and hand washing along the way when on trips where I'll be camping with water available. When boondocking, I fill it to the top.

I prefer to travel with full water tank, suspect its about 24-30 gallons. Be prepared for no water at destination.

I've honestly never given any thought to filling my FW tank before leaving the house. Now I'm starting to wonder if I should. Most of our trips are between 1.5 - 4 hours from home. The one thing I would be concerned about is our FW tank is in the front of the TT putting a fairly considerable amount of weight on the tongue.

Should I fill the fresh water tank full?

My only concern if my tanks have water to them or not is If I am overweight. Water weights just over 8 pounds a gallon. My fresh water tank is 50 gallons. 400 lbs for water. Since it is just me and a dog so if I only half fill my tank that makes up another person to add to my total cargo weight. The trucks can handle another person but will my trailer be over weight.

I would expect the manufacturer has taken the tanks being full into account when designing the unit, I personally never drink the rank water and only fill it a third when traveling to use the facilities. I have yet to boondocks but will eventually.

This is the first discussion I've read thru across a number of forums where someone was concerned about water slosh... I don't have the experience to comment on that. Seems like a lot of people run empty or at least not full to keep the gas price down. Also, I remember a thread that recommended running with full tanks when strong cross winds are expected. Thought was the extra weight might keep the TT upright.

I always keep my water tank at least full as you never know when you might need to spend a couple days somewhere without water service. I also keep the black and grey tanks empty and the fuel tank full or near to it. That way if there's a natural disaster I have some place to live for a few days.

My tank sits on the axles. We can get by for a couple of days with a half tank but usually we just fill it. We have a 40 gallon tank but there is just two of us.

We were concerned about this at the start, too, but in our short experience (6 weeks), we haven't noticed too much of a difference no matter what level it is at. Granted our tank isn't as big as yours, but that seems to generally be the consensus. Good luck and if you do start to feel it sloshing, maybe adjust from there!

Drinking water

Curious after reading these posts. How many drink from there water systems and how do you tell if your water system is good to drink? We bought a 2005 national, 30,000 miles, also if you use it for drinking, how do you treat it each year?

So far , we have never used our fresh water tank, except to test the pump when we bought it, and a few time when a big storm was going and had to use the TT if we lost ele.
When you fill it,do you just fill it to overflow at the fill port ??

We use water tank water for everything, (cooking, drinking, showers etc.),
The water tank and fresh water system have been sanitized with bleach twice, (once in '01, when the coach was new to me, and again in 2012).

BTW that's 2 more times than the water system in my 40 year old sticks and bricks has been "treated".

I always fill it to overflowing. This is especially important when sanitizing so the bleach is in the fill hose. Did you ever see the inside of a fill hose that wasn't properly maintained?

Those that worry about sloshing, do you keep the furl tank completely full or empty? Did you ever feel a slosh from it?
