Temporary Tag or temp Bobtail permit

I'm in Florida and I bought a truck in Arkansas. I when to DMV asking for temp tag to move tractor trailer to FL. DMV told me to get title under my name first, so I did it. A couple days pass to get title, I went back to DMV a different person told me I can't get temporary permit bcs tractor trailer is under my name. I go so F/K mad at them. Now I'm stock with a tractor trailer in Arkansas. I found temporary Insurance without problem. Why no DOT #? I won't drive tractor trailer for a while, a list until i save enough for a insurance and do maintenance. If you know how to get temp tag, please help. Thank you. Happy 4th July....
