Steve,
I have one hose (originally supplied by the dealer) with what I believe to be a Valterra connector on the end (the rest of my hoses are Prest-O-Fit). The orginal hose does fit - with the connector into the clean-out cavivty usually supplied by the end-cap. I can tighten down on the cap enough to create a secure connection. I can post a picture if that would help.

p.s. -- You can purchase pre-fabricated hose carriers, such as this:

My problem has always been how to attach the thing since the attachment holes did not line up with my frame. "The Rip's" suggestion of the 4" pipe clamps (which I could only find at an electrical supply house - not one of my typical stores), were perfect for this job (I don't know if they would work on the pre-fab pipe ??). I have a short pre-fab pipe, that I ordered to experiment with -- I could take a measurement to see if it would work wiith the 4" clamps if there is interest.
