Sounds good then. I totally understand the need to dry it out after the trip. I was worried that if packed away wet for a day, the water would seep through the fabric and get to the bedding. I'm kinda surprised it doesn't honestly.
What is the Eezi-Awn fabric like? Is it really like a heavy canvas? And how waterproof is it? Is it totally waterproof and unbreathable and relies on the windows for ventilation? (Which is fine, just wondering.)
Do they need to be dismounted and stored indoors normally, or can you leave them packed up (after drying) and under the cover on top of a trailer out in the yard?
There is a big difference between waterproof and water resistant.
If something is waterproof it has no breathable qualities. No a good feature on a tent.
A breathable fabric allows the transfer of gases and vapors through the material while keeping water molecules out. Sort of the Gortex theory.
The water resistance of a fabric can be tested using the Funnel Test. A funnel is placed on the material and water is added to it. The height of the column of water is recorded up to the point at which the water soaks through the material.
The balance is to use a material that has good breathability and a high degree of water resistance.
The fabric that is used for the Eezi Awn tents is about as thick as a pair of Carhartt carpenter pants. Due to the nature of the folding of RTT's it's material on material. Add the vibration of off-road travel and thinner material can wear prematurely.
Windows and doors provide for the exchange of large volumes of air, but should not be relied upon to create the micro-climate within the tent. With all the windows and doors closed the tent should breath.
If the tent is put away dry, or has been aired out it can stay on top of the trailer. The only issue you may have long term is a breakdown of the cover due to UV.
