Posting here because its a motorhome reg at issue. Side vent camco reg to be exact.. had regulator creep up when static on a new install. Considering it's a 2 stage and has 2 stages to limit this, it may be more than a one off issue. Coaches without a pilot light anywhere will be the ones affected unnoticed. Maybe when having maintenance done at your next service interval, you could have them check for creep if you have the new camco design.
