If it's the one with the external ribbing and smooth internal surface then they shouldn't hole a smell But ! if it's the cheaper Reject shop version where the ribbing is both internal and external then just dump it and start again with a better quality hose. You could try putting the entire hose into a bucket or plastic box and soaking it in Nappysan, about an hour should do it then flush and reconnect . To make my hose more manageable I have it in 2400mm lengths and join up as many as I need as sometimes the waste outlet is right next to the van and at others it's 30 odd meters away, it also helps to get a straight run to the waste point and easier to flush before I load it into my pipe carrier

Throw it away and buy a washing machine diverter hose from Bunnings. Mine cost less than $10 when I bought it.

Not quite OT but I always got annoyed at the time a sink full of water took to empty via the sullage hose.

Problem now fixed.  I have a 10L bucket to which I have fitted a spigot onto which the sullage hose connects.

Voila!  Now the sink drains immediately into the bucket and can then take as long as it likes to travel from the bucket to the drain inlet.

Flushing it may help, but like the other blokes said, I'd dump it. I have clear, straight plastic tubing the diameter of the outlet pipe. I flush it with carb soda and vinegar, followed by a couple of jugs of boiling water. The way it lays between the van and the drain means it always has water in it, like the U pipe to keep things from crawling back up it into my sink. The smooth straight tube doesn't give anything a grip either. I empty it out frequently and then flush it. When I'm on the road I store my hoses on a weldmesh rack welded to the underside of the A frame. No left over water to spill inside wherever you stow it, and no stink in anything. No matter how often and how much you flush these drains there will always be some stink. All the best and safe travels.

We have ribbed on the outside, smooth on the inside, I have also fitted a brass screw on tap fitting on one end of the hose and when I disconect from the van I screw the hose onto the tap and flush it out,  not had any stink so far.

Thanks for the info you guys i will try all of your suggestions.

I like that "modified" bucket idea, I might try it
