In terms of technology, drivers will need to become proficient with their Qualcomm system, as well as any GPS systems that they are using.
Depending on the in-cab arrangement, many drivers bring their computers, TV's, etc., on the road with them.
Drivers with smartphones and good data plans often use them in place of computers to stream video, video-chat with family, etc.
Regardless of what company you choose, your truck will almost certainly have a Qualcomm system installed in it.
In short, the Qualcomm is a messaging system, usually with a built-in GPS, that drivers and companies use to communicate.
Many drivers bring their laptop computers with them on the road, and everyone has a cell phone or smart phone, these days, so if you have space, and have the power arrangement, you can really bring whatever you want with you.
Keep in mind that many companies have specific policies regarding the size of inverter that drivers can use, or don't allow them at all.
Most of your time will be spent driving, sleeping, or eating. In the event that you get some free time on the road, there are a lot of possibilities, both in the truck and out, for entertaining yourself. Many drivers bring their computers, or at least an internet-accessible phone, with them to keep in touch with family, watch movies, etc.
Many drivers live like they're homeless, not keeping a home base, or apartment, etc., and their time off or "home time" is spent on the road finding cool things to do wherever they may be.
