Question:
I assume the holes in the back are for mounting. Does it come with the appropriate size screws for this purpose? Thanks.

Hey Richard, welcome back. Those are vent holes on the back of the JR Products Vertical 2-Stage Propane Regulator item # 37207-30365. They balance internal pressure and also serve as a relief opening in case of overpressure.
The 2-Stage Propane Regulator item # 37207-30365 has a 1/4" FPT inlet x 3/8" FPT outlet. It is designed to only be used vertically. For a horizontal option we have the item # 37207-30385 with the same 1/4" FPT inlet x 3/8" FPT outlet.

The 4 threaded holes on the back are for the brackets that mount the regulator to your camper/5th wheel.

Thanks for the speedy response. I'm referring to the other side of the regulator. There are 4 holes that look like they would accept a screw of some kind. One of the videos you have for the U-Post RV LP Gas Regulator Bracket (Part Number: 37207-30405) shows what I'm talking about ("Detailed Breakdown of the U-Post RV LP Gas Regulator Bracket").
