No matter where we store our trailer, we leave the roof vents open all the time. Our current unit has three vents with MaxxAir covers over them.
We've stored in the high heat and humidity of South Carolina as well as at home up north without any issues.
We have a neighbor from northern NY who keeps his 5th wheel in Myrtle Beach year round; they use it from October thru March. In 2015 they forgot to leave the vents open when storing it for the summer. It was the only year that they ever had mold develop.
Myrtle Beach, SC Georgia and northern Florida is not like the Florida Keys.
According to all our neighbors here and the local RV dealer in Key Largo, it is imperative to keep the RV closed up as tight as a drum.
Most here do that and use a pouch (don't know the name) with a very dangerous/ poisonous substance that requires a breathing mask to install it and a day to air it out.
I was looking for a "an equal" that is not that bad.
We are from NC and every summer do as you do, but that won't work down here in the Keys.
