Panel Trucks

1947-1955 GM panel truck seats

Thursday, July 26th, 2012


Attached are some pictures of the correct 1947-1955 GM panel truck seats. The right side was a factory option. This would be special ordered if the owner was planning on two passengers.

Though they have been recovered with cloth instead of factory “leatherette”, they are correct in all other ways. What is interesting is how GM made the optional right side seat to fold up against the dash. This was necessary to allow easier access to merchandise up front. No need to unload freight to get to the front storage area.

It appears the seat frame and floor is painted the original grey color. A thin sheet of insulation is placed between each of the body supports. This was to lessen road noise and slow some heat from entering the cab on hot days.

Another interesting feature on panel trucks; the single horizontal oak board on each side of the interior helps prevent damage to the exterior sheet metal walls. If a stack of transported items tipped while the panel truck was making a corner, there was less chance of dents being placed on the sides.

Note the long metal lid over the tool box which is under the factory optional right seat. This is only provided in the panel truck and canopy express bodies.

Panel Truck Wood Floor Changes

Thursday, February 11th, 2010

The very practical panel truck produced from the early 1920′s through 1970 was an excellent cargo vehicle. Merchandise was protected from the weather and equally important from easy theft. Being a freight hauler, its cargo floor is like the pickup truck. Hard yellow pine and cross sills support the weight and merchandise slides on the metal strips.

Though not obvious, a major floor design occurred in the 1/2 ton panel truck in 1950 of the Advance Design years. Prior to this, the floor consisted of about six wood panels, each separated by 1/4″. Covering this gap was the necessary 1 1/2″ wide metal bed strips. To prevent dust from coming through the wood plank separations, GM changed the bed to a single piece of 3/4″ marine plywood in 1950. It appears this was the same size that was used with the flat floor board Suburban. However, with the panel truck the plywood was grooved for the bed strips. Once installed in the truck it looked like strips between the earlier individual planks.

The reason for the new plywood design was to lessen dust entering the storage area (at least in cool weather).  Most back roads were dirt and gravel.  Thus, owners complained that small amounts of dust would come in between the bed strips and settle on merchandise.

With the change in the bed floor, the length of the strips were reduced from 82′ to 79 1/2″ at least three of the punched holes in the early and late strips are in a different position.

One Piece Panel Truck Floor

Thursday, February 11th, 2010

Beginning in 1950, GM introduced an improvement in the cargo area of the panel truck and Canopy Express. It now followed the example of the Suburban by using a one piece, 5 ply floor. This replaced the planks that were always used in the pickup.

GM implied this would better seal dirt and dust from an otherwise closed area used to haul merchandise and food products.

The following data and picture is as removed from a 1950 pamphlet announcing new features for that year.

1947-1955 Deluxe Panel Truck

Thursday, February 11th, 2010

During the first half of the Advance Design years (1947-1955), GM offered a special panel truck as an option. This deluxe model was designed for a company wanting to give a more upscale appearance to their retail customers.

During the era of one car families, the lady of the house looked more toward home deliveries for essentials. GM knew there was a demand for this type panel truck in nicer residential neighborhoods. They targeted stores and shops that provided home deliveries. With a relatively small investment GM added a chrome and stainless steel trim package that gave their pre-existing panel truck a very special look. The chrome grill and bumpers plus stainless trim around the windshield and side door windows was already being used on the deluxe pickup. GM then created some extras for their panel. Three horizontal strips at the lower edge of each fender, a long narrow horizontal strip toward the top of the front fender, and a stainless edging surrounding the two rear door windows added to the panels appearance. Wheels were body colored with three stripes, not black as on the standard model.

The slower selling one ton panel was also available with this deluxe option. This nicely appointed larger panel was right at home in new exclusive suburbs delivering carpet rolls, furniture, carrying pipe for the plumber, etc.

Production of these Advance Design deluxe panel trucks was ceased in mid to late 1951. Korean war shortages and the resulting high cost of stainless steel eliminated this optional package. After the war years this deluxe model with the many horizontal trim strips was introduced again as the 1954 through mid 1955. With limited production, the short lived optional deluxe panel truck is a very rare sight in today’s world. Locating the necessary parts to transform a standard panel to a deluxe model is now nearly impossible.
