I've used our RhinoFLEX hose for probably 4 years now and see no need to replace it until (and if) it starts leaking. We use our fifth wheel at least 8 days each month (99 nights this year so far) and it's been stepped on and abused but still doesn't leak.
So - I'm hoping for at least five years or longer.

I'm still using the original Presto-Fit Blue Line I bought 10 yrs ago. I have replaced the coupler once after a senior moment engaging the lugs at the valve and breaking off the catch, but other than that, they have been great

Whenever the door to the sewer hose compartment breaks off on the highway, and the hose gets sucked out.
Let’s see...that’s once.
I had that happen ONCE with my previous fifth wheel (hose stored in the bumper). Evidently for several miles I had a tail flopping up and down off the highway until another driver told me. Of course, the connector was beat to a pulp and I had holes in the hose.
That's when I bought RhinoFLEX.

I used a Thetford SmartHose for four years before it started leaking at the coils where it contacts the pavement. During that time we camped about 350 nights, so it was used well over 100 times. (We seldom stay in one place more than three nights.)
The replacement SmartHose that I bought leaked the first time I used it. I called Thetford and they sent me another one that was fine.
I just looked on their web site. They no longer have that exact product, but their "Titan" looks like it's the same stout hose but with conventional twist type connections. The SmartHose has quick release connections like large industrial hoses.

Used a Rhino flex on our seasonal site for 8 years with no problems. Replaced it 2 years ago to insure there would be no problems. We use a section of pvc gutter to keep it out of the sun.
