Advice for former LEO retiring and going into trucking

I'm already in school and paying my way. 50 year old cop/investigator, prior combat infantry vet looking for a change. I've been looking at this field of work for almost a year. I could do many other things as PI, back ground investigation, outside the US corp security etc., but I want to step away from LE field all completely.

I know I can work hard, without griping. I know I can pass any and all clearances for this job or any other testing for endorsements. In 35 years of driving I've driven all kinds of military trucks, combat vehicles, farm equipment, fire apparatus and brush trucks, basically everything except a class A combination yet. And I like to drive, even x-country and outside the US. I can count all accidents in my life in one hand. One in Germany for rear ending another vehicle while checking out a chicks ###. I was 19 y/o. Another time I was ran off the road on a snowy pass by a 18 wheeler and crashed into an unoccupied illegally parked car too close to the road. Other 2 accidents were intentionally done on the job. Let's just say there are many ways to stop a murderer evading the cops that are not on the books. The other was a head on and by his choice.

I'd like to hear the recommendations. If you have a negative reply, please articulate. If is to bad mouth trucking or newbies don't bother to reply. If you want to bash cops, go to a cop forum. I'll no longer be one and could probably outdo your cop bad mouthing if there were a competition, The only reason I mention it is to provide perspective. I'm positive there are other former cops that could give me some insight.

I appreciate this in advance.
