Well, it lasted 15 months. That rig does the monthy semi refueling station where the semis run over and park on our hose. It has been pulled across asphalt and rubber commercial roof well over 1500 times. It has been at jobs where it had to be suspended over 120 ft spans 8 hrs a day ad been dragged on the asphalt countless times while moving the truck.
Got the first pinhole in it a couple of nights ago.
I am satisfied with that service interval. Especially since it is 480 ft coninuous. It popped at the 30 ft mark. I will probably try to fix it at least once.
