Bob,

There is an interesting debate out there on a 12V-71 in an MH 9500 Long Nose. Some say there were some made, others say there were never any made. What is your say on it?

My pleasure to all who enjoyed my post.

As for a 12V-71 long conventional: I don't think any were 'officially' built by GMC. Such a truck would have been an MP 9500 ('P' denoted 12V-71 in an Astro 95/Titan 90). I know a few MH's were converted to 12V power and I wouldn't be surprised if GMC built a few prototypes, but I don't think GMC ever sold one, not even as an SEO. Incidentally all the Long Nose M series trucks got the raised cab in 1974. They also had the grille with 2 low mounted headlights.

1977 was the last year the Astro 95 and Titan 90 offered the 12V-71. The General and Bison never offered the 12V. The 8V-92's made the 12V-71's redundant in highway trucks.

I know car haulers are different but we had a bunch of single headlight 9500s. The stinger trucks (5th wheel behind rear tires) mostly had 6V92 but the conventional trucks (5th wheel over the tires) were mostly 671s. I don't know why but most of them did not have the GMC script in the grill. They we not high cab models as every company looked to get as low as possible.

I believe some of those trucks did not have the "GMC" letters as some manufacturers did not want to have a different brand vehicle pulling their brand of cars.

Trying to fool the public, but we knew better, lol.

Also, even though they may look low, the trucks above are still considered high cabs, having the larger radiators in them.

Newly acquired c8500 in the snow(sleet). Putting a 17' dump body on it.

An ex power company truck?

Yep, Public Sevice Gas and Electric out of NJ. Had about 90 of these same trucks all under 20,000 miles. They cut the buckets off of them so they were pretty useless as they were.
Max speed of about 57mph made for a slow journey back to North Carolina!

PMT used to debadge their Volvo trucks too

That will make a handy dump truck.

I'll be checking that out better when I have more time. Lots of info!

[C10 - C90 Bill]

No need for a Snow Plow on that truck.

[special-K]

That's what I was thinking. Was it's suspension lowered or was it castrated into a 1t with the hubs adapted to run big wheelz?

High, mighty, and handsome

[C10 - C90 Bill]

Nice looking 7500. Wondering what it has for an engine.

[70c10-08]

GMC. A big name in trucks with some great little news. From 1982

That General is carrying trusses like I used to carry them on my '71 9500 Flat Bed Dump. And sure enough, once I got to the job site I would need to dump them off as there was very rarely any fork lifts available. It took a special procedure to get it accomplished and victory was to have them on the ground just like they were when on the truck. The good 'ol days, lol.

I just had a load of trusses delivered like the General!

[special-K]

I never see trusses hauled on the proper truss trailers anymore. Maybe because they are so damn big they are too tall, need to come with flat top to add peak trusses on top. The proper trailers had a single center bean with cross bars of steel tube front and rear. The ends of the tub were angled down, and once taken loose they'd get slid off the side into a stack. The framing crew would have to tidey up the stack to be stacked and aligned, unless they were ready to start hauling them up into place. The plant near here carried them on roller flatbed on their sides, with the peak hanging way out the side. I can't believe the troopers allow it. They hand off the right side farther than allowed off the rear. And those jockeys haul butt right on down the road. Real sketchy once off the interstate onto the local roads.

I would love to find an old S10 long bed 4wd to run. Wouldn't mind having a General, too but...

This trailer was adjustable in a couple of places so that they could keep the height below 13'6". The framers had a Lull and were able to take them off and place them where they wanted them. The trusses came out of Canada. Most of the time around here they come on the roller flatbeds but they have to have an escort.

[C10 - C90 Bill]

Hauling them the way we did, Height or Width was never an issue. On a 20Ft Flat Bed though, they were pretty long. Most trusses were 24's some 28's but I once hauled a set of 36's to a commercial job site. When at the site, the dumping process was to first remove the rear chain, change the front chain to a rope, then remove the 2 X 12 that supported them at the rear. If the trusses did not start to tip back on their own, you needed the give the rope a little slack, then go to the rear and use your weight to tip it backwards. Then go back to the rope and ease them down till the back side were flat on the bed. Then carefully dump them off till the rear hit the ground, tilt the bed down some, then pull away. On those 36's, once tipped back, then dumping them before they slid, how high was the top tail in the air? I'd be only guessing, lol, but you needed to be careful of wires and where they would land if they were to go sideways.

When I started making a living with a hammer and a square in 1971 my dad was building out a subdivision. All the houses were a basic 28'x72' footprint with floor plan and street elevation changes. We stick framed all of them.

By the time I put down my hammer and moved to the office in 1995, trusses were usually stacked because roofs were so damned high.

Dumping trusses is definitely an art.

[special-K]

I've gotten some free trusses due to damage

How do you figure these were hauled??

[C10 - C90 Bill]

Those sure are monsters.

[NewBayColony]

I framed for awhile in the early 80's and we stick built everything except one house and I don't remember why we used trusses on that one.
