You got a nice rig. APUs are a chronic headache but, you need them working for all of the no idle states or you'll be going without sleep again.
I'm sure customers, idiotic drivers that cut you off and, dumb truck drivers will try your patience a lot more. They pay isn't great starting out, but it gets better. My husband earns a salary of $68,000.00 annually and, he drives just 520 miles per day. he's home every night and home weekends. That's the top of the line for a driver. He's been working as a freight hauler for 7 years, drove tour trucks before that so, it takes a bit to "pay your dues" but, not as long as many other careers and, it's a stable, transferable job.
As long as people need to eat and want to live in towns and cities, there will be a job for a truck driver and, the moving nature of the job means you can work for anyone and live just about anywhere. We live in AR but, the company my husband works for is in IL. he hasn't been to the terminal (they only have one) in 3 years at all. His truck lives in our yard when he isn't driving it and, the maintenance man for the company loads up the service truck and, comes down here when it needs serviced. Repairs are done at whatever shop is closest when it breaks down.
The company, just 80 trucks, treats us like family and, I'd love to give you a referral but, their insurance requires you have 24 months experience. One exception - if you live anywhere between Dallas, TX and Texarkana, TX there will soon be a dedicated, home nightly run opening up and, the owner of the company is willing to bend the rules and put any driver my husband or I recommend on the run. For that run, the driver has a leased truck from Ryder so, all maintenance and such goes through them. It is a city cab so, no sleeper, would have to live along the route so you could go home to sleep.
