The route that I took was around 30 years ago but it worked out great for me and a few friends that I know.
I started working for an LTL trucking company in the evening on the dock loading and offloading trailers. I made friends with the yard dog guys and asked if they would mind helping me get familiar with operating heavy equipment. I started doing this after my shift ended but quickly learned and transitioned from the dock to the yard. I ended up acquiring my CDL through this company all the while getting supplemental income and all the seat time I needed.
With the right connections and your willingness to work at it this could be an option for you too.
And my personal preference is the early 2000’s KW single cab, chromed out, with white rock lights and a cool sound system
