I agree precooling does not help with the ability to quickly reach set point. But crap happens at any time. Going into a temp controlled shipper without being precooled is just dumb if for no other reason than knowing your system has not taken a dump, and can achieve set point when empty. If it can do this empty, you can load with at least a few more degrees of confidence
And I admit I don’t run pretrips as often as I probably should but we run new[er] equipment and don’t change trailers very often.

With a reefer load of produce you must take a temperature reading from the middle of some of them pallets, if you have a company in a hurry they only cool it so the outsides are the right temp. IT will take a long time to get the rest to required temps. If you get the core temps and notify and have that listed on the BOL you might have covered your rear.

I remember pulling over in Alabama one summer night when that reefer was really working hard, roaring actually for a really hard long time that evening.
I checked it's information and come to find out that she was dealing what it thought was around 170 degrees around it.
I actually dropped the trailer facing the wind at a truckstop and waited a hour over dinner. I came back to it and she had settled down into what it thought was only 135 or so. I ended up staying there backed up to it until morning light. It really calmed down in the night. (That might have had something to do with less heat etc also)
I normally run the hell out of my reefers, but when they get to demonstrating a behavior of someone hurting (It's weird to some people but it's easier to explain in English) I tend to nurse over it more.Another Canadian driver Thanks this. -

I just finished reading all the post.
These posters really did their homework and
know more than a thing or two about running reefers.
Very helpful replies.
I hope the OP got some good insight into what's going on.
He should post an update with the outcome afterwards.
Good luck OP. -
Did you pulp the load as shipper loaded it ? , used to be part of the drivers job to pulp and write temps on the bills.
If the load was loaded warm it would never cool down , maybe the top tie if your lucky.
Is the load SLC.Another Canadian driver Thanks this. -

Combination of hot product, warm ambient temp, and a smaller unit, they really recommend the 310/330
For frozen, although I do quite a bit with my 200, I can only get to about 0 on ~85+ degree days.
i would manually defrost it a few times as well
