Hi Ron,
Your 2013 Montana 3150RL has two propane tanks so you'll want a dual stage pressure regulator with automatic changeover. The automatic changeover will switch from the main tank to the reserve tank if the main tank were to run out of propane. The JR Products Compact Automatic Changeover 2-Stage Propane Regulator part # 37207-31525 will be perfect for your camper's propane set up. The low-pressure 2-stage regulator combines high pressure first stage and low pressure second stage into one unit to ensure a continuous flow of gas to all appliances. It's rated for 262,500 Btu which is more than enough to handle your RV appliances propane demand. The 37207-30395 is a vertical dual stage regulator, so if you have a horizontal regulator, you'll need to use the JR Products Horizontal 2-stage Propane Regulator part # 37207-30375. It combines low and high pressures same as the other regulator but is rated for 225,000 Btu and doesn't have automatic changeover. While the automatic changeover feature is great, you'll need to replace your regulator with one that has the same vertical or horizontal orientation to allow for proper draining of water out of the regulator.
How is your current regulator oriented?

Ron, I have a Grand Design 315RLTS. I smelled gas and replaced my regulator. Very easy install, if you know lefty loosey - righty tighty, with basic tools.

Ron, this regulator is very good at doing what it is designed to do. Unfortunately for some of us, this regulator is NOT a mount ready replacement. The original equipment regulator on my 381TH had 4 screw mounts on the regulator. The replacement does not. Just be aware that some trailers have different mounts
