KDyer - I just purchased a 2020 TC LWB and was stumped by the fact that all the 12v outlets remain on when the van is turned off. I have a dash cam that is plugged in and while it does not draw much current the idea that these outlets remain on seems strange. I've read a little about possible built-in delays or voltage regulators that switch them off when the battery gets low but cannot find anything in writing for certain. Today I did a little experiment and it appears that the outlets will remain powered for about 15 minutes after the vehicle is turned off. Experiment for yourself just in case there are some anomalies between models or years.
