Why does the truck go into deep sleep on a battery tender?

How do you have it hooked up to battery? Are you including the BCM or not? My guess is BCM still thinks it’s low voltage. Try getting full charge and reset BCM.

Battery tender hooked on the battery

If both leads are directly to the battery terminals change it. put the black lead to a body ground or to the top of the sensor connected to the negative terminal.

You need to include BCM is my understanding. Other wise it thinks battery is low.

Yes. The ground lead must be connected before the BMS plug. Grounding to the body is the easiest way to ensure this. Once connected, the BMS can sense the incoming charge.

If it’s factory battery you may think about upgrading it. Mine was a H6 that’s pretty small and stick battery’s suck. I went H7 and interstate brand. No more issues

If your truck is not a Powerboost I think I read could take up to a H8. Will need a new blanket for battery either way. So pick a battery then order the blanket to fit.

Yessir, I was planning a Duracell H8. I have a 5.0!
