Also, there is the issue with where you park your truck. After all, he already warned me about every morning checking the tank cap (if someone stole your fuel), the engine (if someone stole the battery) and the exhaust (if someone stole the cathalitic converter).

Diesel stealing is extremely common where i live so leaving your truck in the open is asking to getting your diesel siphoned. And you also have to pay toll on the main highways around here, so operating by yourself is pretty steep.

Also there are fines and whatnot, but the average logistics company around here takes 10K in fines a year and still turns massive profits. As a self employed chump, they'll probably fleece you alive
