RV source references: manuals, recalls and regulations
Use the actual equipment manual for operation and service, the regulator’s campaign record for a recall and the responsible authority for a route or license rule. Keep the model, year and document revision attached to the figure. A similar product name does not establish that the same instruction applies.
Start with the question and its controlling document
| Question | Document or authority |
|---|---|
| Unrepaired vehicle recall | NHTSA VIN search and manufacturer campaign records |
| Propane-cylinder qualification | PHMSA guidance and the cylinder’s actual markings |
| Driving entitlement | The issuing state’s complete license and endorsement rules |
| Appliance operation | Installed model’s owner manual and applicable service notices |
| RV construction standard | Applicable edition and actual unit certification |
Useful starting points include NHTSA recalls, PHMSA cylinder markings, California DMV license classes, RVIA’s adopted standards and Lippert’s In-Wall owner manual. A state example is not a nationwide rule, and an older manual is not automatically the revision for current equipment.
Two similar recalls can cover different production ranges
The KZ 21V-670 campaign instructions and Holiday House 22V-067 notice both concern Winntec 6020 regulators, but their stated manufacturing-year ranges differ. Do not transfer one maker’s campaign applicability to another RV merely because the component model matches.
The recall guide compares the actual code ranges and VIN-lookup limits. Retain evidence that a remedy was completed; an appointment or an empty lookup result is not the same evidence.
Compare specifications, owner reports and asking prices
A maker’s dry weight, an owner’s loaded scale measurement and a dealer’s advertised price describe different things. Keep the configuration, load and sale conditions with the number. A single report is not a reliability rate, and a conditional asking price is not a completed transaction.
Use the references beside each brand comparison, system guide and maintenance decision for those specific facts. Record the actual assumptions when using a calculator; a computed example is not a measured performance test.
