You can get the proper regulators at an RV store.
IIRC, most RVs are something like either 10, 18, or 20 PSI regulated at the bottle for the internal system (i.e. any heaters or inside stoves - the main regulator steps down from bottle pressure to one of those PSI numbers depending on size of camper, manufacturer, number of appliances, etc.)
You will need to find out what your stove takes as far as inlet pressure and step down to the appropriate amount.
Most gas grill regulators come from bottle pressure (@ 250psi) to about 7-11" water column (roughly 1.7-2.5 psi).
