Closing RTT's when wet?

Ok, another question...

What happens if you have to close up an RTT after or during a rain shower? Say you're moving camp, take it down in the morning soaking wet and zip up the cover, drive somewhere for the day, then set it up again... is the installed bedding now wet?

No, with a high quality RTT the bedding will not be wet.

Due to the moisture in the air the bedding may feel damp but no more so than when you put it away.

In situations like this it's always best to open and air the tent as best you can when you stop.

Yes and no...
I notice that with the opening design of my Hannibal and the fact that the rain fly comes off to pack it away that I can get rain inside the ends of the tent when opening & closing.

But lucky for me I live in Arizona where it isn't much of a problem

We sold Hannibal tents for a few years and we never took the fly sheet off to pack them?

Are you taking your's off because you want to, or because you have to?

Your bedding should stay dry even if the tent is packed wet. What you don't want to do is pack a tent wet and leave it for a long time. You'll get some very nasty mold growth on the fabric which is hard to wash off but not impossible. In my experience (Technitop, Hannibal, Ezi-Aawn) the tents are pretty well sealed from the factory. Just keep in mind that in South Africa, where all the ones I mentioned are made, it doesn't rain very much.

The Karoo or the Kalahari, Ya

Cape Town in the winter when it rains plenty, or the Garden Route where it rains lots.

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.

I slept in my Overcamp during a week of torrential rain last spring, put it away wet every morning and left it like that all day. The inside walls of the tent got a bit clammy after a couple of nights but never wet to touch and never transferred any moisture to the mattress. I got wetter faffing around with the cover.

Cheers,
Graham

Martyn, I believe you can have waterproof and breathable, it's the Gore-Tex you mentioned. My Drysuit for whitewater kayaking is Gore-Tex, you can be immersed in water all day, no water gets in and it breathes. If a Gore-Text Drysuit is $750+, a RTT from it would be very pricey.

I've read about their Immersion Technology and I like the sound of it. I'll be interested in how it performs over time.

The technology relies on a Gore-Tex membrane inside the outer fabric and I wonder how that would hold up in the high energy environment of a RTT.

I spent 20 years in the ski industry and still got soaked through wearing expensive Gore-Tex gear. So I'm hopeful but cynical.
