Depending on how your tank or tanks are oriented, this might be a bad idea.
In our 5th wheel the drain outlet is on the left side, but the tanks face towards the back of the camper.
Tilting our camper to the side would leave several gallons of liquid and lots of solids behind.
In fact, our best option is to raise the nose, but since that would mean disconnecting, a level dump works best.
If you have a galley tank, it can even be oriented different that the black tank.
That could make your technique worse (or better) depending on that tank's orientation to the other two.
