How old was your last RV? The “new” OPD tanks became a standard by law around 1998. Any tank from 4 lb. to 40 lb. were required to comply. Tanks need to be re-certified every 10 years and cannot be re-certified or filled (legally) unless it had an OPD. So it sounds like your local propane folks might be cutting some corners.
Anyway, swap tanks are just purchased tanks that are new or have been re-certified. No difference in reliability, quality or “strength”…..unless of course the swap tanks are managed by that same shady propane dealer.
For what it’s worth, a propane refill station near our camp would fill whatever you brought him. For us that used to be a few 100 lb. tanks every fall at the start of hunting season, he just didn’t care (or follow the 80% rule). Occasionally on a warmer day one or more of the tanks would vent gas because he had overfilled them and the safety valve would release a bit to relieve some pressure. How we never blew ourselves up is a mystery.
