Brand new Class C owner and RVer

Your sewer connection is standard. New hoses are reasonably cheap from Walmart. Higher quality from RV stores if you want to pay for it. We are still using an inexpensive hose. Some folks take the hose out of the bumper and put it in a PVC pipe with end caps mounted underneath for the purpose. Won't rust the PVC etc. But we have not had issues with putting it in the bumper lately. I did have a bumper cap come off and lost a connector piece, but now I have the bumper ends taped on and one that has a little latch for the hose cover. I have seen RV hoses on the highway--not uncommon to lose the end cap and then the whole hose!
