From description on etrailer.com:
"High-pressure regulator is designed for high-demand propane equipment, primarily used for dual-bottle psig setups with distant separation applications. Regulates 500,000 Btu/hr or 30 psig based on 100 psig inlet."
The red regulator reduces the pressure from tank pressure (100 psi) to 30 psi before sending it across your rv to the auto-switchover regulator which reduces the pressure further. It's for safety.
yup. every 5th wheel I've seen has this arrangement. Unlike a TT with the propane bottles external and very close together a 5th wheel has propane tanks seperated by a reasonable distance AND inside the trailer. So the high pressure regulator is a safety precaution.
