I think "hot shot" specialty hauling is a pretty good gig if you can get hooked up with the right clients.
Hot Shot is definitely a good one. I see broker rates for light 40’ hot shots paying as much or more as I get for full truck load 48k lb 48’ flat bed.
Hot Shot loading is the easiest way to get in if you can get tied in with the right people. You’re hauling for yourself and can find loads you can do yourself to where you want to go. Still have to hustle to make good money but it’s possible.
