1974 Mack U700

[67RModel]

Can't say that I have ever seen a 700 series U model. Would be nice if there was some more pictures and specs. Probably a pretty scarce truck. Not mine. Just reposting and passing along a Marketplace listing I thought was interesting. It looks slightly different than the 600 series U models I have seen. The front fenders and grille look to be about 4"-6" taller.

Curious what engine is in it.  Gerhart's has a Cummins.  That's the only one I've seen.  Besides the tall hood they used the shallow cab

Southeastern Freight Lines has hundreds of Cummins-powered U-700s. They were continually pleased with them.

I thought that Roadway had Detroit engines, whereas as Lexington, South Carolina-based Southeastern had Cummins, what with Cummins being popular in the Carolinas.

have said it before ; this BMT site teaches an ole man new things all the time. ALL the years of seeing the big R fleet  never realized they were U-700's not standard 600's!!

little bit of fiberglass rework and the hood becomes a DMM

If it is a gold dog on the front which it says it is then I would imagine it's Maxidyne 

 Guessing a 5 speed and it's on 44 rears 

Would imagine it's 6 cylinder but there's no reason it couldn't be a V8 Mack, so 325 V8 is possible 

Would of thought it would have a V8 badge on the side of the bonnet if it was 

Still is a different looking ride to me, certainly would be interesting bob tail

Looks like 20 inch rims with maybe 12.00 tyres, or maybe 11.00

Certianly doesn't look like 10.00 x 20's

I have no idea about the mileage, wouldn't be many cars or farm utes of that age with so few miles, l can't imagine a truck staying so young 

Tyres would still possibly have factory air in them ha ha 

I reckon it's a ripper truck

It has a chrome dog, and thus a vendor engine.

If I had to guess, a U747ST with a 350 Cummins.

[mrsmackpaul]

Dunno, the add says it's  a gold dog and the dog looks gold in the photos 

And if it was chrome it may be a Thermodyne

we had 3 U700 short frame tandem tractors back in 79 at Kings supermarkets. 

rode like crap no trailer, but they were great in the city. 327 5 speed trucks.

hehe single axles with spring ride were horrible with no box,,,but just as bad as everything else back then,,bob

That gold bulldog must have came with the same can as the gold grill and headlight trim.  Would be interesting to know more about this truck though. I remember a local concrete plant had one ( where's Steve S ) If I remember correctly it was a single drive, tandem taper leaf suspenssion and a V6 Detroit.  U700s must all be some interesting combination of components 🤷‍♂️  Interesting truck just the same.

Don’t know, man I’m confused. Mack salesman told me a long time ago if it had a gold bulldog, the driveline was all Mack lol getting different stories here seems I do remember they only use them a few years kind of came and went either way. I would like to have that one. Mrs mower I’m sure it has a different opinion ha ha… bob
