Only one mention has been made of having/obtaining the proper type drivers license!!
If a course is found, the instructor should know enough to advise. Otherwise it's up to you. Fla. statutes appear to use the 26,001 lb. breakpoint for having a form of CDL (for non-com'l use) - class B - that other states use.
Without the proper license ones insurance is tenative at best and if stopped, a citation is probable.
