Part of my problem was that my stove needed a high-pressure regulator and the heater needed a normal 11" WC regulator.
He gave it a look and scratched his head for a few days and suggested rubber propane line for the heater but automotive steel reinforced rubber hose for the high-pressure side. He was concerned with leakage of the numerous fittings I would need if I went with the pipe.
Here's how it looks:
The fact that the lines are rubber made for an easy run without additional fittings (that could leak). Both lines go up through the floor and are sealed off with Lexel sealant. I measured what I needed and he cut the hose and crimped the fittings on. Any propane business can do this.
I'd do it again this way if need be.

I broached the same subject with my brother, a commercial plumber, last year (for a stove and heater that are both 11" water column). I got a similar answer.
I asked him what he thought would be best, copper pipe, annealed copper tubing, steel pipe, braided hose, etc.
He replied very quickly: "I wouldn't use any of them. Just run rubber hose. It's easier, won't shake the joints loose, and will handle vibration better. And you can probably get the right lengths off the shelf."
I plan to seal with a grommet and whatever compatible waterproofing goo I have available at the time.
