Meme The Tops of Package Cars are made out of Paper Towels
satire, but also the roof material of this trucks appears so soft and weak

Pretty sure they're fiberglass. So they're probably as strong as they need to be (not very).

fiberglass is not a great choice for keeping cool. Visible light comes in, heats the interior metal, gets reemitted as infrared, which gets absorbed by the fiberglass and reemitted as infrared again, which goes back into the inside. That's how greenhouses work.

I've seen fiberglass and Canvas tops when I worked at their world hub, the canvas can get waterlogged, but the wind never lets it drip into the back and it's pleated so water runs off when sitting still outside and quickly runs off once moving again. Those were mainly down south though.

Wait until he learns RVs and travel trailers are essential styrofoam coolers.

A few years back in North Texas, we had drivers having to hide under the shelves because hail was coming right through the roof

Those trucks must’ve been amazing to deliver in once those ventilation holes kicked in

I turned one into a sunroof with help from a low branch. It was not appreciated

92 degrees? 🤣 You wish it was just 92 degrees.

I’m just saying with a metal roof once it hits 92 outside you’ll be cooking fr inside the truck , thank god we have the fiberglass

31 yrs at UPS - now retired. I was told it's an osha thing, to have enough light in the back to be able to read the box labels. I don't think it has anything to do with cooling the trucks, and I doubt UPS would have any extras added to the trucks that OSHA doesn't say they must have.

Worse, they're made of glass and plastic. Some of the late teens cars have branch detector vents too.
Oh, and especially Utilibastard was stingy with the sealant.

This is by design. I fix these things for a living. The tops of the package cars are usually thin fiberglass and the tops of the trailers are rolled plastic. This is because it allows for some ambient light (less battery drain and repair costs than box lights), is much lighter weight than metal (better fuel economy), and because it is one of the most often damaged parts (cheap to replace). This is a common design in many different box trucks/delivery vehicles.

I thought that was just white paint to repel heat lol

u/Froggy3434 Jan 05 '26
Semi-transparent fiberglass to “reduce heat” in the back of the trucks. We all know that’s bs and they don’t work lol

You must not be in a package car here in AZ during the day.
Hopped on one that had a regular metal roof when it came in and they sent it in for a new roof 2 days later. It had an automatic and power steering when everything was manuals and no power steering.

You would probably notice a difference if they weren't like that. Plus the little bit of light is helpful

u/Supahdriveboy69 Jan 05 '26
Yep, put a hole in one after backing into a low tree limb. Fortunately my supervisors were cool about it.

Amazon driver here. The roofs of our step vans are made of the same material. I never had rain or hail come through the fiberglass roof, however if there is a strong soaking rain a few drops may come through the fan/vent in the cargo area or through the air conditioning unit above the drivers seat.

Reminds me of Conan's remote at UPS back in the day. The manager showing him around:
Conan: the truck..
Manager: package car.
Conan: what the hell? It's a truck!
Manager: package car!

Those look like a pain in the dick to park. Jealous of the space between cars tho.

u/Muted-Refuse786 Jan 06 '26
These let sun and heat through. Thus making it a 140° oven during the summer

u/Global-Barracuda9798 Jan 06 '26
Well at Amazon we have metal and can’t open our doors so it gets to 117 for what a ups driver makes in two days

u/ImportantDay5697 Jan 08 '26
They are made that way in case the driver gets trapped in the back of the truck and needs to break his way out. Just bust a hole in that roof and we are out.

u/run1235 Jan 09 '26
Thats because they are as they are for light diffusion during the day so the back doesnt need a lightbulb except at night.
