Hey, Lori-
How are things going in Jersey? This is very random, but it came up in my homeroom discussion and I was hoping you could help. I know your dad and your brother have a trucking company. We were wondering how they kept the freezer and refrigerator going when the truck was turned off? Please don't take any time to find this answer, but if you know, my kids would appreciate it. Things are going well here. I am getting in lots of skiing which has been great so far. I hope to see you soon. Thanks, Maddie.
And this is all I know about "keeping the freezer and refrigerator going when the truck was turned off." Anything for our kids. Anything to improve our image.

Maddie,
To answer your question about keeping a loaded trailer temperature controlled you have to understand that the tractor and trailer are two separate pieces of equipment. (You have to have a motor vehicle registration for a tractor and also for a trailer. Two taxes, one huge and one small. I once got two parking tickets in Long Island City, New York for parking in a no parking zone--one for the tractor and one for the trailer.) If you look at a refrigerated trailer, you will notice a piece of equipment hanging from the front wall of the trailer. It's actually a refrigerator, or "reefer" as we call it in the trade. It is a self-propelled, thermostatically-controlled refrigeration unit. It has its own engine, usually diesel powered although some are powered by electricity, and compressor, just like a household refrigerator. Most reefers are designed to cool to twenty below and heat to eighty above because certain food products require certain temperatures during transit to ensure quality and shelf life. For example: we crank up (start) our reefers and set the thermostat at 34 degrees for apples, lettuce, and strawberries. For a load of ice cream we set the thermostat at 20 below. Tomatoes, 55 degrees. Bananas, 57 degrees. And so it goes. Each food product requires a certain temperature. And some food products are more temperature critical than others--strawberries are much more temperature critical than onions, bananas more so than potatoes, etc. Hauling food products (and all temperature-controlled products) requires a little knowledge of the product you are hauling.
But, it you are referring to the tiny refrigerators (for snacks, water, soda, etc.)inside some tractors, they draw power from the tractor's batteries. When the tractor is off they still draw power, just like a radio does or headlights do when your car is shut off.
I hope I have answered your question. If not, let me know and I will give it another shot tomorrow. Say hi to Liz. And tell her pitchers and catchers report to spring training next week. I CAN'T WAIT! It's not like I want revenge. I don't. It's just that we were three outs away from stomping you again. What went wrong, oh Lord? What went wrong?
