First, thank you for the link.
Like many others, I've wondered what I am going to do on that fateful day when the OEM setup is just too short.
Following the link for the converter I see it's $27.14 plus s&h.
I searched for a extension hose, and found one for, wait for it,
$151.59 --one must really like the cam-lock system to purchase on of these. Free shipping on orders over $100 though.
For me, the goldilocks solution, looks to be a cam-lock hose to quarter turn
(Lippert 360789 Waste Master Cam Lock Male To Female Bayonet Fitting) for
$38.95--I'll be able use my Rhino-hose extenders (if I hadn't given them to the daughter-in-law for her toad.
It's nice to have options
Again, many thanks and happy travels.
