I used to use a handmade laptop mounts that came down in front of the air brakes. 90% for delorme street atlast though id run audiobooks in the background. Last truck i used a cheap 7" pad computer which worked better than the laptop. Id run audiobooks or LISTEN to movies/tv on it (even at home i kepe the tv on it keeps me company. note i DONT watch it). Sometimes use my phone for that and gps. Usually use a roll of movers tape in the cupholder to actually hold cups. Try it.. they wont spill. Ive always kept a small microwave on the right side. Have minicrockpots etc in the cabinets. I used a Heier fridge in the floor when i drove peterbilts. It served as a very stable desk. When in freightliners i have a portable camping cooler i use that is about the size of a backpack. Behind the driver see on the cabinet i keep a 5 gallon water bottle. Everything is held with industrial velcro. Everything.
I want a 27-31" flatscreen with mounts on the sleeper wall. When i outright own the truck im probably taking out the passenger seat and putting in some kind of custom setup. I also want to replace the upper bunk with custom cabinets. I usually use a fouton mattress thing over the crappy truck mattress then 3 or 4 comforters and a buncha pillows. makes getting in the sleeper heavenly
I keep snacks/soup directly behind the drivers seat within easy reach. Wherever the fridge is ..same thing. I keep oranges/apples/healthy snacks in it. I tried one of those chairpillow things to sit up in the sleeper.. didnt work worth a crap. Id love to hear a solution for that one. i guess the real solution is spend $2000 on a high end captains chair for your truck.
