Propane Regulator

I'm attempting to install a propane stove in my toy hauler. I do NOT want to buy the wrong regulator. Can someone please tell me how to choose the correct regulator/hose? I believe I have all the relevant information here:

Stove is a:
SMEV
Model: pi8822s

Label says:

Monifold Pressure: 10 IN W.C.
NORMAL FLOW RATES (BTU/h):
Auxilary
1x 3700
SemiRapid
-
Rapid
1x 6700

I need to get a regulator for a standard 20lb propane tank that will attach to this stove.

Manual is here:
