Nice set up bro. I am doing about the same as you are. I have the Tmobile home internet in my sleeper, Full desktop gaming pc set up feeding to a 42 inch monitor on the bottom bunk and a 32 inch curved monitor up on the top bunk. Hey we spend enough time in these trucks, ....might as well make it more like home in here right? I am a fellow Warzone player myself. When I tell randoms I am playing in a semi truck they all freak out lol. Be safe out there bro.
50 dollar a month 4g hotspot device(a tiny little device) much easier. like your xbox (although maybe get a series s). that's a 2013 xbox you got there. I HAVE a full tower pc in my truck haha
