Different camper, same problem here...
I have the 90-degree elbow into the dump inlet. From that, I have a "Y" (wye) and the hook 2 separate hoses that run to the camper. At the camper, I have either a clear 90-degree elbow or clear 45-degree elbow at the camper connection itself. All of the connectors are the twist/bayonet type.
I lie a little about the 2 hoses - I actually have 4 hoses that total up to 60' of hose (2 x 20' hoses and 2 x 10' hoses). And, I've used all of it before. I've actually kicked around getting a 5' hose.
