I too use a 90 degree fitting with either a "Yummy sewer donut" or a threaded coupler, This is the proper way to do it as it seals the hole so no sewer gasses escape. the old hose in the hole is not recommeneded and in some areas may be prohibited.

I have used mine for many many uses including pulling the jack pads out from under the RV. and the leveling steps. and the sewer hose out of the storage pipe and ... Well about the only thing I have NOT used it for is pulling the awning out since it's a power awning.
