I installed the unit last Friday and only tested things while on the driveway idling. Looks like if you're driving the truck it behaves normally. My commute to work is ~20 minutes and it did not shut off.
It somehow knows if you're idle and turns itself off after a few minutes, I need to look and see if there's a setting to disable that.
For those looking to get it, installation is super simple. Let me know if you guys have any questions.
