I drove semi's (yes, I said SEMI!) for 17 years. Some jobs sucked, others were great, it depends on the company. Just look for newer equipment (with A/C, clean, big sleeper) and if you see a driver around in the yard when you are there, ask them what they think of the place. I also had driving jobs where I was home every day. Again, you want newer equipment and you also don't want a job where you get done at 8pm and go back in at 5AM. They call that a "home every night" job, I call it crappy living! I drove tankers, doubles, dump trailers, refrigerated trailers, live cattle, swinging meat, flatbeds. Tankers are easy to unload, just hook up the hoses, dumps are easy. Flatbeds sometimes were forklift unload and sometimes hand unload. Box trailers and refridgerated freight all depends on the company, some places unload for you, others make you unload. Depends what you like I guess. Do you have a class A or B?
