I agree it doesn't sound like sweating, even though there is probably a strong contrast in temperature, inside to outside, right now in Florida. Perhaps something on the roof is letting water through, trailing down and working its way through a failed slide wall seal. Close the slide and check for moisture on its inside-most frame edges and the top of the coach wall opening.
Air conditioner mounting seals are reknowned for failing, often due to loosened long bolts that are supposed to pinch the outside seal between inner and outer AC housing components. Water then can creep across the domed roof's internal materials to any wall and down. Its a good idea to annually check that those AC long-bolt nuts are snug, but not overtighten. I only go to the roof leak theory because you say the slide top isn't wet, but the water has to be getting into the slideout above the cabinet somewhere.
