Propane Regulator - BBQ style
What is the difference between the two-stage RV regulator with the big vent and the Homedepot ones with no big vent? They are the same 11WC, so is the big vent critical? I think it locks the valve c...

Something you might consider, the single stage regulator may be all you need as long as you do not need to burn more than 70,000 btu/hr worth of propane at any given time. The black acme nut on the single stage regulators are only rated at 70,000 bth/hr which is considered low flow and typically run only one appliance at a time. You might be able to operate 2 appliances inside the trailer at the same time, but not both running full blast at the same time. I doubt the water heater and furnace will run at the same time.
The green acme nuts like on the pigtails commonly used with the dual stage regulators on trailers are rated for 200,000 btu/hr and are considered medium flow. They allow higher flow for running multiple appliances at once.
Lastly, red acme nuts are rated for 400,000 btu/hr. The only place I have seen the red acme nuts in use was on a Papa John's vending trailer used to serve the shipyard here for lunch time vending. I walked by it in the shopping center where the store that operated it is located. It was an enclosed trailer the size of a race car trailer. It had 6 - 40 lb propane cylinders mounted on the front with 3 dual stage auto change over regulators. Each regulator was connected to 2 propane cylinders. That set up allowed 1,200,000 btu/hr of propane flow available for the pizza ovens and warmers inside.
