Could someone please explain the condensation cycle inside a trailer?

I understand that, at night, the relative humidity increases all
around. I assume that the air inside the trailer cools slower than the
air outside, as thus, becomes warmer relative to the outside. Does the
relatively warm air inside the trailer then condensate against the
cold inner skin of the trailer? Is it then fair to assume that the
water we find on the glider is the result of the condensation dripping
on the glider, and not air condensating on the glider itself?

Thanks.

And once the morning warming cycle starts and the surfaces of the
trailer warm up before the high thermal mass parts of the glider the
water may cycle back in the air and condense on the glider. Open some
damp trailers in the early morning and you'll see condensation clearly
on the glider. Once the glider surfaces fall below the dew point
moisture could also condense there, so its not exclusively going to be
on the outer surfaces.

I also would like to see some study of humidity in trailers, all the
folklore and different ideas about fiberglass or aluminum top
trailers, insulated trailer tops, different types of vents and fans
etc. would be interesting to explore. I started to build a data logger
that could capture the humidity and air and surface temps but got
sidetracked and never got it finished. I am concerned that some of the
fans may such in moist air in the morning that condenses and then
takes a while to vent out. Maybe by the time the solar fans really
kick in the glider has warmed enough, but who knows.

The very worst thing probably just a leak either of rain or
condensation on the outside of the trailer. Worth double checking that
any water on the floor of the trailer is not simply from a leak. I've
had both my cobra aluminum top trailers one brand new, one near new)
leak rainwater around the tail fin vent and was a simple matter of
removing and reinstalling with fresh silicone sealant. Worth playing
with a hose and checking out if they leak.
