A blower is then connected to the duct. The blower sucks air in from the outside and pressurizes the RV. A soap type liquid is then sprayed over the outside seams and around the window of the RV. Leaks show up as bubbles. This system is supposed to be able to find the smallest leaks.
You may want to have your RV tested for leaks this way.
Seal-Tec is the name. I have also seen where people did a DIY with an old furnace blower mounted in a wooden box they sit over top of a roof vent. They go by the dollar store and buy a big jug of "bubbles" (the soap solution used by kids for blowing bubbles) and use a garden sprayer.
I am in the process of installing two Fantastic Fans in my new TT. When I'm done, all I will have to do is switch them to bring the air in and start spraying the soap solution.
You can bet every time I wash the trailer I will have those fans running that way (about 3 times a year).

This page has a list of places that have the machine. There is a whole bunch of them in Florida. Sorry I don't know my Florida geography, so I don't know which ones are around central Florida.

When we were researching a new-to-us used fifth wheel purchase, we looked at one with a "small" leak, according to the dealer. In reality, the whole back right corner was rotted through. Pressing my thumb lightly into the wall resulted in a depression in the surface.
Cause was the smallest of holes, a pin-head size hole in the rubber roof. Barely visible, looked like a dirt spot. Here on the Wet Coast, it didn't take much to let water into the wall and rot everything.
We still "test-drove" the unit, and darn if water didn't appear on the rear kitchen counter from the leak. We ran, not walked, away from that deal.
Have also repaired the inlaws motorhome overhead bunk after the front window leaked. The window had settled in the frame and the butyl tape no longer sealed the unit well enough.
In another instance, on another fifth wheel we didn't buy, leaking was the result of an outside hatch door that let water settle on its frame and seep into the rig.
When we finally did purchase, we quadruple checked our rig when we got it home. Found the outsite electrical outlet wasn't sealed watertight to the rig. It was attached but not sealed all around, so water could have been seeping into the wall. Someone must have been sleeping at work that day!

Another item that is common for leaking is the ac seal. The mounting bolts can loosen over time.

hmmm... this increasing list of culprits is making a pressure test seem like a better deal all the time.

We found water on our dresser and the screws that hold the window in place needed to be tightened. Learned that from the service tech, he saved us an 90 mile drive.

I really liked the idea of checking the screws... however they were all tight 
Also, there was no rust. However I did find some staining that looks like water running from under the window. It's an emergency exit window and my guess is that's the issue. Will need to investigate more.
