Wondering if anyone has taken their cats in a trailer? It would seem that they would certainly need to be in a carrier, tied down so that it doesn't slide around. What about temperature? My trailer...
How long are your trips? We used to leave ours at home with lots of dry food, plenty of water, and very large litter box. The only downside(s) are it takes a bit of cleanup around the litter box, and that the cat bitched at us for a couple of hours upon return. But then after her say, she was back to her normal self.
I would not advise putting a live animal or human in the TT in Florida while towing. It can’t be a smooth ride, dangerous, and too danged hot.
