    Hey friends! I'm looking to the internet for advice:typing:
    I've been slowly building out my 2018 Tundra as an all-round adventure, touring, camping rig for a couple years. I've done a pretty good job of keeping my electrical needs fairly low, a couple low draw LED's, a 12v water pump, and the occasional use of an electric heated blanket. well that all just changed with the addition of a 12v refrigerator. The IceCo VL60D.
    I have a new replacement lead acid starting battery in the truck now, but just watching the voltage I know I'm taxing the hell out of it!
    so, at first I weighed the option of just going with a single, dual purpose battery like the Optima Yellow top. but that leaves me really relying an awful lot on one battery.
    so I've landed on adding a second battery in the bed. I'm looking at 100ah AGM options currently.
    So my question is really about charging this battery. over the last few days I've basically given myself a crash course on how the various charging systems work, and I feel fairly overwhelmed with making a decision at this point. I'm looking for simplicity in my electrical system. I'm perfectly competent in keeping an eye on my battery levels, but I don't need the biggest baddest system out there, just something that works. I drive the truck daily, and will be relying on my alternator to do the work for now.. And figure I can plug in a trickle charger when I'm home if necessary.
    Of these three units, what would you suggest? and why?
    Oh, and do these trucks have “smart alternators”?
    What’s working for y’all?
