When the black tube under the camper is provided for the sewer hose storage, the diameter is to small to store the tube with ends on the hose attached. Also it's a cheap, thin flimsy hose.
After one use, I purchased a Rhino sewer hose with ends .. like this: https://www.walmart.com/ip/Camco-397...B&gclsrc=aw.ds
I also purchased some 4" or 5" square white plastic channel, affixed it under my camper to store it - far superior the the factory hose and storage tube.
