Propane Troubleshooting Suggestions?
I'd appreciate any suggestions on how to trouble-shoot a propane problem before I throw any more money at it. Background: 2014 Grand Design 337RLS Fifth Wheel Two 30# tanks (Both full) - Curb ...

See the big 100, 000 BTU regs on 250, and 500 gallon domestic tanks? They don't fight the high pressure reg like your little regulator does. Propane is screwy. Line up two fast fill valves is series and you'll be lucky to get any flow even with a 250 psi delivery.
I used a T on domestic set tanks, one leg with an 11" WC reg to the house the other leg had a high pressure reg to the generator
When space was an issue I elected to use motor fuel 5/16" hose sometimes referred to as liquid hose connected to the POL. The T was then easier to fit. You can if you wish put a low pressure LPG **** valve after the T on the 11" side to isolate. Liquid hose isn"t cheap neither are the fittings. But you can use either crimp or makeup fittings. Makeup fittings are 2-piece -you'll need a vise. Wrap duct tape around the hose to be cut and use a 32-tooth hacksaw blade to cut the hose. A chop saw is better.
This is no Mickey Mouse modification. Liquid hose is insanely tough. I've seen bad installations where the hose wore through it's outer liner and wore a groove in a steel truck frame and the outer steel braid was still intact. Amazing stuff - stiff to bend. Use ells and 45's as needed.
Hope This Helps
