Truck battery randomly going stone dead

[Commander 06]

I am randomly getting a stone dead battery. So my truck sits for 5 days a week I only drive it on the weekends. It typically starts with no issues. But it will randomly have a dead battery. And once I jump start it it will be good for anywhere form 2 week to a month and then it will randomly go dead. I have check every time it goes dead to see if I left something on but never see that I leave anything on. The battery is about 2year old. "I have 2 aftermarket electric devices one is the remote start. This issue started before I had the remote start. And a aftermarket backup camera/ dash cam in the rear view mirror. If I leave the mirror plug in it will away drain the batter that is what I check first to make sure I did not leave mirror plugs in... is ther anything I may be over looking to see why my battery is going dead randomly

You do not provide info regarding having the battery tested, the charging system checked, or performing a voltage drop test/parasitic loss test. Start with those.

Battery needs full testing (not the cheapo electronic testers on amazon). Not uncommon for a 2 year old battery to jump ship early.

PS: My Caddy did that and it was the head unit / radio draining it.
