Non-Frozen Food Items in Freezer Compartment

I have done less and less of the precooling as my trailer is out at a storage lot. I just start the fridge, transfer items from the cooler and roll out direct from storage. An ice cream bar may not make it intact but I have no issues generally. All seems fine upon arrival at camp.

OK to precool also if needed. Your list sequence is fine.

Any items that are not pre-cooled can stay in the box until the next morning to reduce the burden to keep the perishables cold.
