Now , not meaning to be too OT...

Yet another question arises ... Wouldn't this be a good time of year to install aluminum siding on a trailer ? ...

Deductive reasoning would have us believe since the metal is "expanded " that it would be forever tight ... Cold weather , it would just get "tighter" ...

I don't know about TD s , having never done one in aluminum , but I see an awful lot of CT's around here just wrinkled as a (your word here ) in the Heat !!! They must have been assembled in Cold weather ... Some are still tight as a drum in this hellish heat ... What's the real story on this ??? Does that make sense in the real TD world ???
