Dunno what you have so I'll toss this one out from a thread a long time ago.
If you have an anti-freeze position where the pump draws from the 1gal containers, drop that siphon into the potable water tank.
I'm sure there are other ways, but next I go to the outside shower with a hose jumper built to go from the outside shower faucet and into the street fresh tank fill.
Start pump and open the faucet. Takes me around 2 mins to drain a 7gal portable potable jug.
That is exactly what I do as well. So easy.
