I sold all my oilfield trucks, bought two newer Peterbilts and running them for a specialized company that does shows, slots, concerts and so on. The only thing good about the oilfield is the pay and you end up paying a price for that with long hours, on call, never knowing when you will see home again and so on. Unless you are working for a service company with an office job. Yard jobs they will work the crap out of you even. But the rigs, 28 days on and 28 (example. they are all different) off which usually ends up ( according to a lot of people I know that work on the rigs) 28 days on and then maybe 2 or 3 off maybe a week. Then they call you because someone quit or got sick or just failed to show up. Really good pay though. But a lot of people get fed up with it for a lot of different reasons. In the oilfield, my truck would pass a DOT inspection either roadside or in the scales, nothing extra. With this new company my truck passes an inspection, I get 75 dollars and the driver gets 50.
Office jobs would be OK but I would stay away from the rigs, the trucks, the service companies, the docks and so on. But that's me and only my opinion. Some love it, some hate it.
