For those of us with push start, how do we keep the truck accessory mode on? It times out. We have no key to leave in the ignition. Anyone have success doing this with push button start?

read your owners manual!, it explains how to put the vehicle in accessory mode so it does not time out after 10 minutes

To keep the Accessory in ON position for keyless vehicles, put the vehicle in service mode.  This may be the solution.  It's described in the owner's manual:

"Service Mode

This power mode is available for service and diagnostics, and to verify the proper operation of the malfunction indicator lamp as may be required for emission inspection purposes.  With the vehicle off, and the brake pedal not applied, pressing and holding the ENGINE START/STOP button for more than five seconds will place the vehicle in Service Mode. The  instruments and audio systems will operate as they do when the ignition is on, but the vehicle will not be able to be driven. The engine will not start in Service Mode. Press the ENGINE  START/STOP button again to turn the ignition off."

2020 Silverado with push button start - I was able to open the doors exit and lock the doors and it stayed on.  It did NOT time out and shut off after 20 minutes..  On to step 2 - rigging a charger will enough amperage to keep the battery up.  Anyone know what the amp draw is in accessory or Service Mode?  Does anyone know if the trailer maintainer in a trailer will keep the truck charged on a 2020?

I use a 5 amp battery tender on my 2018. Used it 4 days straight like this. It started normally.

Interesting thread here. Lots of good info. I’ll be boondocking in Montana where there’s no shore power or cell service so I don’t have the same goal as OP but it is good to know more about how our trucks work and can work with our campers.
