You’re talking about a trickle charger every night? I’m probably too lazy to do that haha.
Ha!
But you can make it easy on yourself like I did without much effort.

I put an SAE plug next to my charge port in the truck, connected to the 12v battery.

Inside the truck it is connected on the 6mm bolts with ring terminals and a 6mm nut, the negative downstream of the BMS sensor.

Inside my garage, next to my FCSP, I have a Noco Genius1 I can plug in to an outlet, and I ran an extension for the battery maintainer through an RV access panel I use for the FCSP cable.

In cold weather I plug the truck in to my EVSE anyway and I have the battery maintainer wire right next to it so doesn't take much time or effort.

It takes me less than a minute to connect the SAE plug to the extension and then plug in the NOCO Genius1.

I figure having to replace the battery, or getting stranded somewhere and needing roadside assistance or a jump would be a lot less convenient and use up more time and maybe money too, if not still covered under the warranty.

It's an ounce of prevention, that I believe will pay off in the long run.
My 2012 Nissan Leaf AGM 12v has lasted 13 years, kept on a maintainer when not being used.
