I've seen 5 window cabs on 47 AD trucks. Take a look in the gallery.

Deluxe option, from what I've read here on the forum was available on 3 window or 5 window cabs.

Hopefully someone will be alone to confirm what year the deluxe option was started

Exception may have been during Korea era.

As posted above, a 5-window can was available as an option in all Advance-Design and GMC New Design years. In some years, the 5-window cab was available without being part of a "deluxe cab" option.

I you are picky about cab details, I think the 47 and 48 cabs had a slightly different firewall compared to later years. Also, you probably know that the early cabs did not have an opening for an in-cab fuel tank.

I thought the 5 windows were an option on their own, and deluxe was a trim package.

In 1947, RPO-387 was the Rear-Corner Windows (only) option, and RPO-390 was the De Luxe Cab and Equipment Option which included the rear-corner windows.

Which year are you referring to? As posted above, there were differences, depending on the year.

I thought the deluxe option was the corner windows. I was unaware there was also a deluxe trim package. Glad to have you guys around.

What year?

For many A-D years, RPO-390 was the De Luxe Cab and Equipment Option which included the rear-corner windows.

RPO-390 (and RPO-387) from the 1947 Chevrolet Truck Data Book

What is the unicorn that you are searching for? A unicorn is a legendary (mythical?) creature that most likely never existed, except perhaps in fairy tales.

Did you look in the Gallery, as suggested by DADS50?

They exist and are a little different from the later year cabs, including gauges, under bed gas tank so cab does not have filler hole, the 47 and early 48 came with a 3 speed floor shifter with parking brake lever located next to the shifter so no left side parking foot brake. firewall is smooth] with no raised strengtheners and the 47 does not have a cowl drip rail. (notice the steering column hole will not accept the 3 on the tree shift mechanism, this is 47 and early 1948 only)

If you don't mind non-original and want to convert your 3 window, use any cab from 1947-1950, not many people will know the difference and you will have more choices.

The 1949 i am getting today has a chrome grill and is a 5 window cab. On the heater under the dash it says "deluxe".

That heater (if it is a 1949 GM heater) would be the accessory Fresh Air heater (the outside air type heater on this page).

That's not the "Fresh Air" heater, This is what a Fresh Air heater looks like, notice it does not say "Deluxe"

This heater has the Deluxe tag, not sure if it's the same.

Here's another Deluxe heater

Was the "de luxe" heater available in 1949? Maybe in early 1949 - it is shown in the 47/48 Truck Data Book, but not in the 1949 TDB.

Or, if 5/8 ton's heater looks like the earlier de luxe heater, it might have been a later addition or a dealer-added older heater?

So what's different on a 1947 5 window cab? I'm trying to figure out what year my cab is. thinking somewhere between 47-50 it has an outside drivers vent as well as fins on the pass side. The inside is like my 51 3100 except the rear of the cab coners is enclosed and there's a enclose strip down the center. This does not look like someone put in it looks factory

Quick difference is no gas filler hole on the passenger side 1947/1948, 1949 was the first year to have the raised sheet metal indentations on the firewall, the cinch strip for the cab windlass was screwed in 1947/8/9 and spot welded in 1950 on.

My 49 has no raised indentions on firewall. I noticed that last night. I thought it started in 49 also. Maybe this is an early 49

There were also a variety of other differences between early and late 1949 cabs/trucks.
