With our small 21' TT, I use DampRid... but, I found that the hanging bag seems to work much better than the bucket. Nothing scientific, just seems that the bag fills with water much quicker than the bucket. I go through about 2 bags a winter depending on weather, and 1 or 2 during the summer during extended periods of not being used.
This is up in New England, so I have no idea if this will help you down in Florida.
