Popping sound on trailer

[Aftonomos]

Might be a dumb question but I can't seem to find much info online.


My toon spends it's time away from the water covered on a trailer.  Seems as though each night I can hear one, sometimes 2 loud popping noises.  


I'm assuming this is normal from the heating/cooling of the log, but want to make sure it's normal.  I'm not sure how these toons are constructed internally...hoping this isn't a sign of a loss baffle/bulkhead or something serious.

If it's sitting on the trailer, might it be the springs settling?

I suppose that could be the case, but after 7 days of sitting/not moving I'm thinking it could be the hull(s).

Depending on the what material you have on the trailer rails it may be the toons moving on them.
