If you use Hydraulic hose which has a Nitrile tube the propane will leak through the tube and become trapped under the non pin pricked cover. This will create little bubbles of gas under the cover.
The hose used on forklifts are rated at 350PSI Working Pressure (5x1 safety factor) as are most all Propane hoses. The forklift hose has a stainless steel braid to add extra strength if the hose catches on something and for longevity from the weather.
It would be a great choice for a Teardrop. However, It will, as designed, allow the Propane to seep through the cover, so it must only be used outdoors in a well ventilated area. (UL21) Don't use Propane hose in a confined area!!!!
FYI: I run a hose shop and have been building, specing, testing, and selling hose for 40+ years. I am BCHD certified hose specialist. Our shop builds and hydro static tests/certifies thousands of Propane per year. We hydro test ALL Propane hoses to RMA specs of 2 times the WP (700PSI) for 10 minutes.

I have learned not to argue with folks that know more than I (and even not to argue with "Big" Guy (Teardrops for Vets), even though I sometimes doubt his "facts" as he goes for the jugular (twice on each side) and won't let me know when I'VE WON the argument). Your explanation that propane hoses are designed to leak baffles me and seems to defy "common sense" that hoses carrying flamable gasses should be "gas tight". All serious leak testing is done with helium as it is the smallest element in its natural state (one helium atom even though hydrogen is smaller but hydrogen is actually two hydrogen atoms in a molecule). Propane is a big molecule (compared to a a water molecule) and it's surprising it gets through a rubber hose. I called a big hose shop and they confirmed your statements. WIERD. Learned something today. You'd think with modern materials they could make a hose that doesn't leak!
