The thread prompted me to look on the Internet. I have not found the hose that comes with machined stainless ends this time.
RV water filter store has a lined drinking water hose reinforced but it looks like machined brass fittings, which is better than plated tin but still...
I have been intending to go to a marine store when near one and look at what they have as stainless is preferred around salt water I believe.
Any strong quality hose is going to be a bit stiff. I found two listings for polyurathane hose, imagine the stiffness. I am not able to crawl around under our mh now and figure out how to store a hose reel. Stiffness is not a real big issue on a powered reel of the right size. 50' of hose 3/4" good hose is going to be bulky and heavy. I have one compartment that would be just right....but it houses my electrical cord. Wet Bay may indeed work but would require some work and changing face panels with controls and digging back in deep if need to replace. Camco which CW carries, on Amazon has a nickle plated machined brass blue hose with fax printed black reinforcement cross pattern for 22.00 or so.
There was at leas one moe site probably 100 more, that had industrial food grade hoses cut to length with machined brass ends. At an RV rally, in La several years ago there was a Vendor who made custom length hoses with heavy stainless machined ends, but was using reinforced clear hose which is a no no as algae, and other things likes to grow in it with any sunlight. If you sue 1/2" hose it will be more easily rolled up and should handle all the water we need, if you can find good machined heavy ends, brass plated super thin steel ends are a a real big problem. I didn't see listings for hose reels for RVs this time but they are there for sure.
This is one reason I want a new, faboulous darling, as Zha Zha says coach with hoes an power cords on powered reels. Just push a button and out they come.
Save lot of bending and fiddling with stopping the leaks and replacing hose washers which usually destroys cheap brass plated hose ends. Need a hose, next time I see you I got a plenty in a compartment, wit the thin hose ends, depsite throwing out a great many. They can be coiled easy and thrown in the dumpster easy too.
