Hi There JoeyD!
The subject of "TIRES" is probably the single biggest topic but I won't start a tire tread because it is such a contraversial one. One thing certain, be sure to use a good trusted tire gauge and maintain the proper tire pressure. I was surprised to learn about the tire gauges I relied on. You can read about it

Watch your air filter closely. Don't go by mileage alone. How often depends on how clean or dirty the air is where you travel. Traveling a season through forest fire haze will prematurely dirty-up the air filter. One year in our first rig, I had a new air filter at the start of our trip, but just one afternoon driving in Monument Valley required a new filter the next day. A simple visual inspection works well for me. The in-service filter can appear clean until compared to a brand new one.
It seems that around the 40,000 mile mark is when servicing the transmission (fluid & filter change) becomes a good idea for "severe service" like a motorhome. Don't by universal transmission fluid. Be sure to get exactly what is stated in your Ford manual.
As always, make sure your power steering fluid is at the right level and your coolant as well. I don't know the recommended coolant flush schedule but I understand in-general it is based on miles driven. Coolant doesn't get old sitting inside a radiator and engine block. Ethylene glycol doesn't break down, but the added rust inhibitors do when the coolant is heated. I recommend using the same coolant Ford used whether adding or replacing.
As far as your brakes are concerned, you being in Florida, you are in a very humid environment. It is wise to have your brake fluid flushed every 5-6 years. If you don't drive your PC enough, severe surface rust on the rotors will reduce brake performance and also the life of your brake pads.
I am sure there is more, but this is what came to mind at the moment.
