Are you talking about the little white plastic gripper wheel? I have one on my TM, and yes, it is very helpful. I think I salvaged mine off a cheap plastic water pressure regulator that failed. You will also see them on the shorty 6-inch hoses that supposedly save your water hose from excessive bending. They are also available as a stand-alone purchase at some RV service counters, though surprisingly pricey ($6 or $7).
Check out Dyer'sOnline, item number 98859, for example. PPLMotorHomes also has it for about the same price Item 88-1427.
