If your truck is sitting for a long time outside, add a solar panel, 100w or 2x 100w panels would do the trick.
The Ctek D250SA mentioned above has support for solar. Sitting for a long time would kill a battery pretty fast. My truck sometimes sits for two months, so I have an external charger to top up every 2 weeks.
If I had a CTEK D250SA with solar, I wouldn't need to plugin a majority of the time.
But TBH, even a $20 solar maintainer would probably do the trick.
Long term build wise, you can look into a Smart LVD from Victron w/ Bluetooth to protect from over usage drains. The LVD would hook into the house battery and you would simply isolate any non-vehicle tertiary loads through the LVD. The 65A model gives you up to 780W of max draw which is enough for a fridge, aux lights, small inverter. Major secondary loads (Winch, Compressor, etc) I'd leave on the starter battery.
