WW - another option is to find a "decent", used trailer that'll fit all your stuff for sale in PA, use it to haul your stuff and then sell it in FL. That's what I did multiple times for Navy deployments - for example, I'd buy a used trailer in San Diego, haul my stuff to TX for storage at home for free and have my dad sell the trailer. Then, just before my ship would get back to SD, he'd buy another one and after hauling my stuff back to SD, I'd sell it.
I started doing that for my second deployment when I figured out how much it would cost to store my stuff in SD for 10 months.

$800 ($80/mo)
Then I found out it would cost $250+ to rent a trailer 1-way (1978). I found a good-condition used one for $325. Also did it for the stuff I didn't trust movers for PCS moves - foot lockers of bayonets, swords, knives, pistols, rifles, shotguns, and ammo.
Edit - I see where bighoss had the same idea while I was typing mine.
