    • I see that plug under the drivers door and I was wondering how can I find out what is doing? Does it have a block heater or whatever is warming up, or just charges the batteries? Any info on that will be helpful. Thank you!

    Ok, here it comes another question in my head, do you think I can use power cord from my APU outlets inside in the the truck and plug it into that block heater plug? How many watts is that block heater because my Invertor is 1800W?

    Block heaters usually range from 1000-1500 watts.
