The usual value I've seen for the low-pressure side of RV propane supplies is 11 inches of water column. 7 to 10 inches would be close, and would roughly correspond to 1/4 to 1/3 PSI, but I assume that ".7 to .10" is just a typo.
So yes, low-pressure gas grills (but not typical camp stoves) tend to expect the same pressure as RV appliances, including stoves used in trailers. I would just buy a new one, since as Dale suggested they are readily available, but I think the leftover one should be fine for testing. I would also expect the regulator to have its output pressure shown on the case.
