High pressure gas line

So I completed the installation of a 3/8" stainless steel tubing h.p. line from the propane tank to the gas grill location.

Take this for what it's worth :W - but I'd question whether running a high pressure gas line along the underside of the trailer meets code. :h All trailers I've ever seen first regulate at the tank then send low pressure along that line ... even Fleetwood's regulated high pressure feed as used on some of their popups was created by regulating tank pressure down to ~ 16 p.s.i. at the tank and splitting it off with a T to send to the curb side of the trailer for connection to a regulated high pressure stove. The second leg of that regulated T was then regulated a second time down to low pressure and fed to the rest of the trailer. If running full tank pressure which can be anywhere from 80 to 200 p.s.i. met all code requirements then why are no trailer manufacturers doing this? :h
