Getting my CDL soon, what's this REALLY like?

I was brought here on a quick google search, some kid talking about how OTR wasn't what he has looking for, I don't really care what the jobs are, I'm after the money. My current job has me clocking in illegal amount of hours, working OTR and being forced to take a break after 10-11 hours of driving would be a cake walk. So what I'd like to know is what it's like actually working OTR; dealing with things out of your control, getting ridiculous timelines, waiting for a load/unload, unexpected emergencies (flats, brakes go out, ect.) Basically -what are ways that you can get *screwed* by your employer. How often are you guys asked to do the impossible and what is the out come? I drive a 26ft truck governed at 65mph, sometimes I get timelines that wouldn't happen even if I skipped time and drove 150mph straight through rush hour traffic. What happens when you get to your designation and have to wait an entire day because the company your delivering for decided it was a good idea to have 50 trucks come in all at once with only one guy in the warehouse? How does the pay work, I'm located in San Diego for reference. What types of rigs/ jobs are best? Fresh out of CDL classes, should I look for hazmat, should I try flat beds, should I go for fuel rigs, what pays the best or which has the best environment (say the money is all in closed trailers from coast to coast, but a stupid amount of issues from one point to the other, then you're dealing with diminishing returns and actually 'x' thing is better even though the pay is not as high). I'm ready to work and make $$$, if it makes sense. I won't go from one ####ty job to another. Thank you for any info!

 

No I don't have my CDL yet, I'm starting classes next month. Works busy and I like money, so I'm taking the hours they have. I'm just looking for info before I commit, no endorsements, I'm as un remarkable as any newbie comes, but I'm willing to put in work, I just need it to makes sense.

 

That's hardly a deal breaker, but does that usually affect your timelines? Will the timelines be made with this in mind? I'm really looking for some straight talk on what OTR is like
