Long Hauler: 1964 GMC Suburban 2500

Jamie just showed us a ’56 Chevy shorty, so would this one-ton 1964 GMC Suburban 2500 be considered a longy? It looks like a somewhat simple Photoshop exercise with those unusual windows on the side doors and almost the exact same wear on the both doors as if one of them was copied, but this is a real truck. This long hauler can be found here on craigslist in Lewiston, Idaho, right on the western border with Washington state. The seller has a $7,500 price listed. Thanks to Ken for sending in this tip!

Yep, here we go again, there are basically three exterior photos and there is only one photo showing the whole truck from the side, or at an angle showing most of a full side – arguably its strongest selling point. There are no photos at all showing the driver’s side?! We’ll have a cure for every disease known to humans before we ever figure out why some sellers don’t provide enough photos in an online sales listing. But, you’ve heard that too many times from me, sorry. Hey, I only want the best photos for our readers! Ok, back to this stretched Suburban. From what photos they do show, this looks like a solid truck.

This really looks like a solid example, something that we would never see this far east of Idaho with the road salt here. They do include a photo of the underside and it looks rock-solid. The GMC 2500 is a one-ton truck and the seller says that this is a custom build from the Coach Motor Company. With the sliding side windows, I’m guessing that it would have been some sort of passenger vehicle.

Here’s the only interior photo and it shows us a huge cargo space behind the cab, which would have been nice to see. Were there seats in this rig? They show a photo of the rear roof area and the roof-mounted lights make me think that this may have been some sort of school bus or another type of passenger bus? The seller says that it has a 4-speed.

The engine is, I believe, a 305E cubic-inch V6. They show a photo of a tag listing the engine as a 305E with 142 net hp but they have it listed as an 8-cylinder. It runs and drives well, according to the seller. Any thoughts on this stretched GMC? Was it a passenger bus?

    Sure would make a great camper, or small house in case you get into trouble with the war dept. Coool rare body with the extra door and clean, Don’t ever see something this clean that hasn’t had the bejesus beat out of it. Wonder how it sounds with the duals? If the Jimmy mill works out good leave it or swap in a sbc for reliability. Good luck to the new owner!!!

    With that color, the air inlet and bullet lights on the roof I’m instantly thinking some kind of ambulance or fire truck. However, according to the Coachbuilt site Novelty Carriage Works converted to bus production in the late 40s.

    If seller’s story is right, maybe it simply served as a combined bus/ goods hauler for the mentioned Indian reservation?

    Are the side windows in the back original??

    I believe the original was lapping glass with no (metal) frame at the lap.

    Just when you’ve seen just about every oddball variation of 50’s & 60’s trucks/4×4’s, something different pops up.

    I have seen 3 somewhat similar, all were originally EMT type vehicles that also doubled as ambulances. One had also been used to haul forest service firefighters.

    Again, just WOW. The 305V6 is probably the best feature, a bullet-proof engine. And wasn’t the 2500 a 3/4 ton, even in ’64?

    The pistons were the size of coffee cans.

    I had a ’60 Chevy Apache 1 ton.Looked liked this,but in much better
    shape,& only 5100 miles! It was originally a small fire department ambulance.
    It was,like this,20 feet long.
    It was probably the coolest vehicle I’ve ever had,& I never heard a
    negative comment about it.
    I sold it because it was too nice to be kept outside in the Winter.

    Wasn’t the V6 part of a modular engine where they made a V12? I think I saw a GMC V12 one time. Wouldn’t that make a cool custom hot rod! Would need a 100 gallon fuel tank to go 200 miles between fill-ups😂

      The 702 V-12 got a lot of its parts from the GMC parts bin. However, the block and crankshaft were purpose-built as a V-12. They were essentially (2) 351 V6 engines otherwise…

    Glad to see that big ol’ v6 in there instead of a swapped in 350.

    Cool rig. Craigslist seems like a contest for bad photography.

    Sweet looking GMC Suburban. This looks like it would make a great restoration project, or a good daily driver with some careful modifications to it.

    That V12 gas engine pic is fascinating, thanks geomechs. What was it commonly used in?

    A guy I worked with in the 80’s had one of these from the late 60’s. Six of us fit easily going to lunch. One time he stopped at the lumberyard on the way back and loaded in 8 sheets of plywood. It all fit and the rear doors closed with room to spare.

    This style extended hauler was used for “crummies” to carry loggers out to sides and back. Maybe a fire dep’t rig? Most of the logger ones were thoroughly used. Wasn’t the GMC V6 a 306 cid? Unique sound, too.

      It looks to me like it’s a front passenger door just moved backwards!
