Trailer Covers-will that eliminate condensation inside ?

[[email protected]]

I saw a Trailer cover offered. Seems to cover quite nicely a standard Cobra trailer. Color is white.
I wonder if this a solution to reduce or eliminate formation of condensation inside the trailer walls, especially metal ones.
I would assume that since the top and side walls are somewhat insulated they will cool down slow enough at night so that dew will not form on them.
What do you guys think ?

We have no clue......where are you?
What works in one geographic area may be poor in another.

So......where are you?!?!
Moon or Mars, you are likely OK.....on earth, may be good, may suck......

I had one for a GRP topped Cobra (DG808 inside) and nearly
never used it except as a dust cover in the barn in winter. It
was big and heavy; quite a task to fit it! Lots of straps to
connect and it needed a lot of storage space once folded, that
was quite a task too.
If you fly in a grim part of the world it might be worth it. It
was a real heavy pain when it got wet, you needed a good dry
clean hangar to dry it.

I am located in Northeast of USA

Condensation may happen as a result of one of these two causes:

* the trailer is full of warm humid air (from a hazy humid summer day in the NE US) and then cools off at night to below the dewpoint of that air. A cover won't help with that at all.

* on a not-humid summer night in the NE US, the air in the trailer may not quite cool down to its dewpoint, but under a clear sky the trailer roof (especially if metal) cools further by radiation, causing condensation both above (not an issue) and below (inside the trailer). A cover may help with this - but only if it is thick enough to have a significant insulating effect.

I have an Avionic trailer. With the factory solar fan, air is exchanged, cooler (drier) air enters before dark and condensation is not a problem.

I thought those trailer covers were more to protect trailer GRP surface finish against UV and water degradation than to prevent internal condensation.

Several years ago a clubmate had similar condensation problems with a
metal-skinned box trailer (I think this is what's called a 'tube trailer'
in the US).

He lined it with 3mm (1/8") white polystyrene foam sheet held in place
with contact glue and said it fixed his condensation problems, though
IIRC he didn't enjoy applying the glue in the confined space inside the
trailer. I'd think the same solution should work for a Cobra and, because
you're pretty much in free air with the top up, the contact adhesive
fumes should be much less problematic.

in the UK this is used as an interior wall liner.
It comes in 500mm x 10m (5 sq.m, 53 sq.ft) rolls at around $5 a roll.
