If you leave it plugged in for 2 days then eventually the batteries will get low and your cooler will automatically shut off and spoil your goods.
I turn off my trucks batteries completely using the switch near the drivers seat (depends on truck). I also take everything inside my cooler home and leave the cooler lid open for those days off, otherwise, it'll smell inside when you first open it when getting back on the road.
The only time I take my cooler home is when I want to give it a good cleaning.
But definitely don't leave your good in there plugged in for two days.
I too take my food home with me and leave the cooler lid open, I also clean it every time i leave for home time. Just a quick wipe down with those Clorox wipes works. Most of the time I don't have any food left in the cooler to really take home.
When going home its always a good idea to leave turn your trucks batteries off. Especially during winter weather. A battery will lose 1.5V every night when the temp is below 30*. I turn the truck batts off and leave my apu on auto, if the batts drain then the apu will kick on an recharge and then shut off when they get charged again.... But not every company has APU's on their trucks..
On tractor trailers, and APU is a small diesel engine that powers a heat and air conditioning unit while charging the truck's main batteries at the same time. This allows the driver to remain comfortable in the cab and have access to electric power without running the main truck engine.
Having an APU helps save money in fuel costs and saves wear and tear on the main engine, though they tend to be expensive to install and maintain. Therefore only a very small percentage of the trucks on the road today come equipped with an APU.

I tried sending you a pm but not sure if you got it or have just been very busy. The question is, do you leave your cooler plugged in to the 12v outlet when you are on home time? I will be home 2 days out of the week so not sure if I can leave it plugged in, or do I need to take everything out of it while at home. I know the instructions say to only leave it plugged in for 4 hours while the engine isn't running. I cannot wait to get it in my truck!
