I'm taking this to mean before starting the engine and with the engine running. If I understood that correctly, then 13.8 is quite high for static battery voltage. If you had the van running right before the battery test then this may support Tim's theory of high alternator output as the battery voltage may not have come down to normal from a state of overcharge yet.
