Welp... Time has told. Two years and it's cracked.
Not many choices out there for a BII besides a dealer ($$$$$$$$$$$, IF they have one lol)... For anyone replacing theirs with an ebay hose (or any hose that is made in China), I suggest wrapping the outside of the hose with some good-quality electrical tape (Scotch Super-88 for example). I'm thinking this will hopefully keep ozone and other crap in the air from attacking the chinese rubber so quickly (and it cracking). Right where it's pushed over the fittings is where it tends to crack, so loosen up the clamps so you can wrap the hose with tape under there too.
Hope this helps someone.
P.S., FWIW the ADS1689 hose did fit my longbed Ranger, though it was a bit short (I had to reposition the hose on it's fittings almost as far out as it could go without it slipping off for it to fit well).
