Cold weather skinning?

Bad idea?
There may be some 40 degree days this winter that might coincide with good weather and a weekend. If I could skin my trailer on a day like that, is it a good idea or bad idea? (This is an outdoor build.)
I know that a 10 foot sheet of aluminum will expand 1/4 inch over about 100 degrees of temperature change.

Assuming full sun beating down on it in summer, that might not be too unrealistic if installed on a cold day. That could lead to some serious oil-canning in summer!
So, here are my questions. is it better to...
1) Trim edges flush to the TD (as per usual SOP with a flush bit router) or trim sheets 1/8" narrower than the wall/roof on all sides?
2) Drill out screw holes larger than the screw to allow for expansion, or not?
3) Is there anything else I should consider? For example, will butyl tape be soft enough to work with and make a good seal on a cold day?
Thanks for your feedback. I am trying to decide whether to batten down the hatches and wait for spring, or take the opportunity to do some skinning if a nice winter day arises. The groundhog didn't see his shadow today, so spring should come early, right?
