That's what I do. I have a Fl 70 with a 24" flatbed on it. It under 26k with air brakes. I haul everything under the sun. I have a Cat engine on right now headed to Atlanta. You can make good money IF you have some body with customer freight. They call broker freight that for a reason. The longer i hauled broker freight, the broker i got! Under 26 you only need a medical card. You will have to keep log books.
Also LTL stands for less than truck load. Right now hot shots are doing good because of freight and fuel prices. They are getting paid say $1.79 a mile with 12-14 mpg vs 6 mpg in a big truck. There are many other advantages that most ppl will never think of. If you need to know anything else just let me know. Be glad to help.
Being under 26k, what does that leave you for room weight wise for a load? Can you explain the customer freight a little more versus a broker? PM me if you need to. This really has my interest right now.
