Confused on fresh water drains

Hello, I have a Rockwood 8280 and run without holding tank water. When we are leaving, we drain the black and grey water. We also have two small plastic drain hoses on the left underside and another drain on the right underside with a flip lever valve.
Do you drain all three hoses or just the right side with the valve to clear the fresh water residual in the hot water tank????

I think the two plastic drains are low points, I don't drain the low points but I do drain the fresh water tank along with the black and grey. When we take off to camp and visit I add a small amount in the FW tank to travel on. Nice to have a port-a-potty along the way.

The two are your low point drains, the other with the lever is your freshwater tank drain. Neither is technically your hot water drain. To drain that you pull the anode in the tank (at least in my TT it's this way).

However, I usually don't bother draining. On average we're out at least every other weekend so I just leave the water that's in the hot water tank there. It's been filtered anyways in the way in, so I'm not too worried about it going bad.

If it's going to sit for a month or more than I'll drain it, via removing the anode rod. That process get's done in my driveway where I can also give the tank a good flushing.

I also have same trailer and the fresh water valve does not empty the hot water tank, only the low point drains or by removing the rod out of the tank. Haven't needed to drain hot water tank for traveling as it ( water) only adds 8 pounds per gallon.

Ditto on it not needing draining unless it is sitting for a few weeks or more. If anyone forgets it's empty and turns the water heater on, it will fry the elements.
You don't leave a little water in the tank for potty breaks while driving??

Thanks for all of the info. I now think I will go the same way as every one else and leave some water in the low drain lines.
