Towing with half a tank
I have a 70 gallon fresh water tank and rarely use 50.Been told that I should only tow empty if possible and fill where I'm camping if possible or tow full to avoid sloshing thus eliminating possible ...

We rarely tow with more than maybe 5 gallons tops. Two main reasons....we always camp with water at the site and we have a Pur filter that mounts on the faucet - improves the taste and water quality considerably. The other reason is that water weighs 8.3# per gallon x a bunch of gallons = more weight and even worse mpg. That 5 gallons or so will get us through bathroom stops along the way and that's about all we need. Only on extended trips do we tow with anything in the grey or black....same reason. Grey is almost always dumped before we head out regardless.
