I have 4 hoses of that size in this RV
1: The original hose that came with my starter kit.. NOW, I do not often need it but strangely it is the oldest hose in the house
2: A Camco Easy Store, this is a hose (20') that comes in it's own storage tube,, I have replaced the hose.
3: I do not know who made it but it's Reddish/Orange and I got it at Campign world this is an Extension Hose (I also put extension style ends on the Starter kit hose and the ez-store is an extrension hose.
My latest is a Tetford "Smart hose" this hose is different first you must have the matching adapters, the hose itself has Cam-Lock ends.
Original assembly was a real pain Took all my strength to push the hose onto the cam-lock adapters.. and at that I needed to use tools on one of the cams. (Pilars squeezed the hose and adapter together till the cam locked easily).
I like the way it attaches to the RV
No problems with it so far
Very nice "Look and feel" to the hose
Does not collapse as much as the other hoses, epically the Rino-Flex (my 2nd) which it replaced. but since I have ample hose storage, NOT a problem.
One comment: Many trailers epically have hose-storage bumpers.. These tend to tear up the hose.. Some folks will lay like a length of Gutter (Eves-troth) cut to the bumper length, lay the hose in the trouth and slide it in that way, Seems to work well..
I use a 7" fence post and a 6" PVC pipe I do have to remove the sewer end of the Smart Hose.
