Getting hired with verifiable work experience, last 3.5 yrs was for cash?

Anyone have experience with getting into a company's CDL training program, getting hired, when all recent work on your resume was for cash?

I've read that it kinda depends on the trucking company. For example, one guy on reddit got rejected from Prime for being 'self employed' for three years (I don't think he filed taxes either) but I keep reading claims that some companies 'will take anyone with a pulse and a clean driving record.' One guy even claimed he blatantly told the recruiter he just sold weed for years, still got hired somewhere.

I worked for one tree service LLC in the last two years that will vouch for me, but there was no paperwork or tax stuff filed. I have verifiable stuff from 2017-2019 too. I'm honestly also way behind on my taxes, they just got all messed up (like my whole life since 2017). I probably have a total of three years since 2016 where I have no verifiable work experience, I was just freelancing in tree work part time and bumming along.

In other news, there are no traffic tickets on my record in the last 3 years, and nothing remotely serious before that. Clean criminal record.

 

I am in Northwest Arkansas

 

edit: I was trying to quote Chinatown with this answer, "Do you have any record at all of being paid, such as a receipt?"

I dont have any record of payment for anything since mid 2019, but the company I worked for after 2021 would vouch for me when they called, confirm dates of employement etc Its just a cash industry, most home owners are willing to pay in cash. Unfortunately for that reason the industry is full of people who are basically pirates.
