G'day Doug,

The Oztrail Easy Fold 1P stretcher is 40cm off the ground, where as the Quest Beast stretcher tent is 35cm off the ground.
Hope that helps!

G'day AD,

Any of the single self inflating camp mats in our range will fit into the single stretcher tent - the most popular options are the Zempire Monstamat, the Sea to Summit Comfort Deluxe, and the Exped Megamat.
As long as you're working within the sleeping area dimensions of 198L x 80W cm, you should be fine.
The mattress will need to be removed for pack up.

G'day Den,

I can see how the C-Clips would ride up the poles and not keep this very taught, this is where the guy ropes come in handy. I would use and peg out every guy rope on the fly and you could even add extra to the eyelets on the fly to help tension this better.

Pegging them into the ground should be fine but it is the guy ropes that create most of the tension for the fly and that helps direct water runoff. 

G'day Den,

These are fully seam sealed and have a 1500mm waterhead rating, so there's no point doubling up.
The issue with these is generally more condensation, which is often mistaken for leaking.  Being such a small space, the area inside heats up warms up more than with a larger tent which has more internal airspace.
Its also common with small hiking tents and swags.

The best bet is to increase ventilation and make sure all guy ropes, etc are pegged out so there's perfect tension across the fly.  After a few years, it may be beneficial to revamp the fly with a DWR treatment that helps water bead and roll off the material, so it's not sitting and soaking in.
The DWR treatment is usually the first to deteriorate, and is the first supporting element of a fully waterproof tent.

G'day Geoff,

Because of the way the fly needs to be connected for tensioning, and the way the frame folds, we recommend removing it for pack up.
Its also the best way to ensure there's no damage to the waterproof fly coatings.
