Many truckers who own their personal 18 wheelers stop in one place close to where their headquarters are. If it is his own personal 18 wheeler and he does not even own or rent an apartment or house then his home is the 18 wheeler. I know some homeless people who apply for a trucking job then save up money for their own personal 18 wheelers and travel across the USA and sleep in their truck cabin.
I have seen 18 wheeler trucks parked outside my hometown or near the highway pulled over the side to sleep for the night then they start up the engines and go to work, driving 18 wheelers. I would not worry about the trucker.
Truckers are usually hard working honest people with good moral values.
