Recommended hose kit
1: Drain master (it's the last hose you will every buy.. Lifetime warranty)
2: Tetford Titan (i think that's the current name) Mine is the older version (Same hose different ends) I really like it. I have a Titan hose in storage for IF (not when) the Sentenal (older version) fails
3: Rinoflex
One thing about the Titan.. IT does not collapse as short" as the Rhinoflex.
THe sewer support (I have a slunky but there are many and Ill not recommend one over the other. Some folks use a couple lengths of gutter (evestrouth) and some wood. I kind of like those)
Some places (Clark County NV for example. includes Lost wage..er. Las Vegas (the Valley) require them Only place I've been that does but ...
They do help the hose last longer.
As others have said Dump when needed. In fact I'm on a full hook up site now I may well not even pull the hose out of the carrier till next week.
(The carrier on my rig is a 6" square fence post which is attached to the frame rails in a place where it's off the ground no matter what I do).
