trickle charge for 120v battery sans AC

I don't garage my Lightening. I've gotten the heebie jeebies about the woeful circumstances than can result from the puny 12v battery wearing down. I don't want to plug in a trickle charger into my house. Can I plug it into the truck? Alternatively, are there battery powered trickle chargers?

Thanks in advance!

I'm so loving this truck (not only b/c I'm charging it with excess PV electrons I've already generated that my util is storing).
I've always had an array of gear in my prior trucks ranging from chains, to strapping to fist aid, to come-a-longs, life jackets etc.
I'll move some of that over but i'm wondering if I need full socket sets and all the other tools (eg screwdrivers, wrenches) for my ICE trucks.

Thanks. I don't have the Pro Charger installed. I've been charging with the 17amp circuit we use with our Tesla (4+/- mi per hr). I turn the truck off when I charge now -- is that bad? With the Pro, the truck must be on which keeps the 12v battery topped off, right?

I was getting a bit freaked by multiple people explaining how important it is not to let the 12v battery run down. I'm thinking there might be week-long periods in which the truck is neither on or plugged in. Should I find something better to fret about?

Thanks a lot.
I only have one bill cycle to compare to but I think trying to charge something for days on 110 will cost you a chunk of change. If you have the Ford charger it is best to go with the 220 outlet it charges real decently on that but not nearly as well as in the lightning charger. However high amperage requires large wires and a sizable fuse panel
