Jamaican Bulldog

This one looks like steel nose or was this another version and not a U?

Did the Autocar short nose U model come in a steel nose with butter fly hood or just the fiberglass hood similar to the White?

I hope Mack trucks, the museum or a large truck club reach out to save this.

I know someone with a still strong running 74 Mack DM 600 with a 237 twin stick. The cab and mounts are bad and he is seeking a replacement. I remember seeing on here that the R and DM models got galvanized cabs in the 80s. When did the Mack DM get a galvanized cab and what year galvanized cab would fit this 1974 Mack DM?

Does carfax work for big trucks or is there an equivalent that exist? Sometimes sites like those can be very detailed to the registration and history of vehicles which could help indicate more of the truck's history before Desert Storm.

Excellent and educational explanations on the single head per cylinder. Is there any reason the American manufacturers didn't adopt this style for its advantages?

Why did the Scania versions of the Mack V8s have individual heads?

While at the factory tour one of Mack employees mentioned that the new military Mack Dump on display is the first time since Vietnam that Mack won a military bid. Do these Desert Storm Macks prove him wrong?

It was made fews years ago I believe by RNK conversions but I do not know any model casters who does them today. I still have an unbuilt conversion kit in 1/24 which I bought over 10 yrs ago.

What is the story of this old dog? Is it for sale?

My guess is mid 70s. Definitely newer than 73 because of the cab

The axles looked like Meritor similar to the AWD military dump truck they had displayed outside. It seems like for AWD applications Mack don't use their own axles anymore just Meritor.

After the truck show at Macungie I took the usual tour at plant. This unusual AWD tractor had just come off the line. It had huge float tires all around and wasn’t for a military customer. Not sure who the end user is or what application but interesting.

Thank you. I build models and wanted to convert a diecast Franklin mint CL into an Australian version but could'nt find suitable pics of what it should look like. Especially the lights and air intakes etc.

I like Australian trucks. Was the Mack CL was sold there along other heavy spec Macks like the Superliner or Titans etc?

Saturday especially if you can make it early is normally the best day. I normally run into the same problem because I usually work Saturdays too. However if I can't get off to go on a Saturday, I try to go early Sunday morning before most trucks are gone and still see most of it

Why did the U.S version have a slightly shorter hood than regular R models here?

Thanks for that info. It seems that is the correct name for that configuration since that style was more appropriate for the Australian Market than the left hand drive DM. Interestingly I am realizing more and more that the resin models I acquired includes Mack versions not sold in the U.S like the R800 and others such as set back axle F models.

Was the R700 model available with a steel or Flintstone hood and if so also a V8? I have seen the R600 with it but the longer hood R 700 model unless they were an export or overseas model like Australia. When I Google it I only see the 600 series. I am not talking about the RD800 model which I know had the steel hood. I build mode trucks and bought many resin kits over the years. I was going through a few unbuilt ones which i bought years ago and noticed that not only do I have a R600 Flintstone but also one with a longer hood with same style. Again not a RD800 which I also have. So I am curious if this model existed. If so I will look to build it according to how it should be.

Not mine but cool old heavy truck. https://www.facebook.com/marketplace/item/2024238677878614/

Not mine but interesting someone would give away a Mack hood. https://www.facebook.com/marketplace/item/2600255206655610/

Impressive as being probably the only true American Truck company that still exists and expanded when others were floundering or acquired. I still find it interesting how it has two similar brands of trucks Peterbilt and Kenworth in the same markets but able to maintain their own identities.

Btw are DM and U model cabs interchangeable despite having different chassis?

41 chevy. That is an excellent explanation! A close look at these pics illustrates that especially looking where the back of the cab meets the roof on both. The DM tapers inward towards the roof which creates the bulge look.

It could be just me but some of the DM cabs looked like they had more of a curve around the belt line than the R models on the back of the cab.
