I'm stunned anyone doesn't know people are moving to the red states. Oh well, fake news.
There's nothing to worry about. Pack your records in double-layered cardboard boxes. Mark them all THIS END UP FRAGILE GLASS. Pack them towards the middle, or anywhere a few feet in from the outside.
This is because the whole trailer is one thermal mass. The outside may get warm but no way the inside temp rises more than a few degrees from ambient at loading time. Its pretty much a physical impossibility. Even on the outside though they will be okay just as long as they're properly boxed up.
