We've been using the Zero-G RV and Marine hose for over a year and love it.
Much easier to handle especially when cold, and stores in much less space.

Amazon has it for $36.96
Make sure you get the RV/Marine, and NOT the garden hose... rubber tasting water.
Yeah, I know.... (sigh)
Bob,
Great idea with the stainless steel mesh hose ahead of the regulator...
We have a quick connect on the rig side, too.
