I actually like the 2-1/2" vacuum hose as first length off the truck mount, but our younger technicians just didn't like the extra weight and size, we pulled them off our Sapphire truck mounts, just running 2-inch now. I do have a supply of 2-1/2" vacuum hose, new in the box, if you guys need any more, just give me a quick ring.
