The Mack Trucks Historical Museum has a Facebook page.

Doug Maney, Curator, recently posted an update on the Museum status on that page.

If you don't do FB, you could ask Doug to repost it here. He has been a regular here for years.

Thank you, I did not realize they had a Facebook page. I was hoping at least the Mack store at Macungie would be open

Sorry if this came up in another trend but does any one know how long the Mack Museum will be closed for. I assume it was closed because of Covid but with so many restrictions lifted I hope will be open again.

Interesting, Do anyone the story behind all those trucks? That's a lot of metal to just leave just laying around. Seemed like they ran when parked too.

I notice some Mack LT or LTL have louvre type grilles and some have mesh style. Did that indicate engine type or were those options no matter the engines or year of build?

Interesting knowledge. For some reason I thought the 2 huskies ornament meant it had V12. Also it was interesting that this concept would compete with the Maxidyne concept at Mack. Did Mack own Brockway at the time it was developed?

I doubt you will find what you are looking for. There may be a chance Mack museum would supply you with some info but they definitely have production information and not ready blueprints suitable to make a scale model. Also a big question is of how highly detailed model you're going to make and in which scale. The chassis is similar to a Superliner and we have its basic measurements in the wiki section. The cab is of relatively simple shape so you can use photos scaling them down. Also being there where you are at I wouldn't miss a chance and get to a real truck with a measure band and take multiple basic sizes to do photo recounts more accurate. If you need a few particular dimensions feel free to PM me and I will measaure one of my MH's.

Thank you , I have since been able to get some detailed photos of a real truck then I will try to do a 3 d image.

I would like to make a scale model and looking for blueprint model of the Mack MH Ultraliner. I searched this website an Google and even though I found diagrams for other Mack Models I could find one for the MH. Does any know where I can find one?

1999 CX Vision (original) CH (still available both set forward and back)

2003 CXN Vision Volvo frame ASET AC engine (CHN set forward steer axle) end of CH set back model

2007 CXP Pinnacle (MP7 only)no DPF  Volvo frame, plus 4" cab new interior (CHN with ASET AC available)

2008 CXU MP7/MP8 DPF Volvo frame plus 4" cab  (same for CHU set forward released)

2017 CHU in set forward Pinnacle only Anthem release

So it seems the change to Volvo frames influenced the name changes. I preferred the names

Not sure what scale it is you are doing but even if its smaller you can use an online scale calculator to scale it down or up

That's awesome, What scale is that? I believe the DM 800 chassis used in the 1/25 scale AMT model truck kit  is very similar. American truck industrial Models in NJ U.S.A does a 1/25 resin RD800 kit and I believe the donor kit is the DM800. I have one but have not built it yet.

I remember with great fanfare when Mack launched the Vision. However a few years later the name of the same design was transitioned to CXU. 

The CH axle forward used to be called the the Pinnacle then they started using the CHU while some versions of the CXU also used the Pinnacle name.

Does any one know why those names were changed on those trucks even though the design/styling stayed the same?

The 673 Mack naturally aspirated and later turbo versions were great economical and reliable engines. However it was to small to compete with the 855 Cummins and its turbocharged versions in the day. Mack's first answer was the 711(never factory turboed) which had its share of problems and it was still to small to compete with Cummins and Detroit. Next Mack went with the 864 V8 but as with the 711 it failed in the market place. About this time Cat entered the scene. Mack just didn't have a big bore product to compete with Cummins Cat and Detroit. Mack lost diesel momentum until the 237/300/350 came along. These were great engines which sold well, but they were still on the small side. The E-7 mechanical was a great engine but again on the small side. By the time the E9 was perfected Mack had lost the V8 momentum. The Mack electronic emissions engines were also problem prone as were other manufacturers engines. If Mack had pursued the "Big Six" instead of the V8 or along side it, they would have been better off IMHO. The present MP-7&8 engines are Idecent engines but still can't compete in the western mountains or Canada. Volvo wants to push their product for these regions with the ISX-15. They would be better off pushing the ISX- 15 in the new Pinnacle. This would put Mack back on the same page with Paccar, Freightliner and VW (Navistar). When was the Reo V-8 first used and how long did its run last. Who else used the Reo V-8 besides White? I see they were 440 cubes and 1200 pounds.

It really seems deliberate that Volvo limited Mack's powertrain choices especially after the MP series came out. Imagine how many Macks would have been sold if they offered Cummins in the Granites, pinnacle, Titan and even now the Anthem. It also seems they purposely designed the newer Mack's to not be able to use engines bigger than 13 liters

Beautiful Trucks.  EVERY ONE OF THEM.  This is my 1985 magnum. This is actually number #1 the very first one ever built. 

Nice! I think I just saw it at the truck show in central NJ about about a week and half ago

I know this is the usual weekend, but   are you sure it’s on?  It does not seem to be posted in the usual event calendars, not even Watts’.  Always a great show but seems quiet. Wrote them and still waiting to hear back.  

I just got a facebook reminder from ATCA old Truckin Nuts page so I guess its on

I am going, looking forward to it

This CL is one of the few CL Elite Limited Editions built. (Less then 150) My one has the E7400 instead of the E9 that was an available option.

Wow, I did not know that paint/decal  scheme was a limited edition.

Saw this in WSJ. Seems there is shortage of drivers everywhere. Some companies are even recruiting airline pilots used to long hours

I guess the front axle would also have to line up with the wheel wells

Some models of the DM and R series were available in both fiber glass and steel butterfly hood. 

However some like the DM800, RD800 and the RM series only came in steel hoods

The steel butterfly hoods were advantageous to give access to servicing especially if you had things like snow plows  or other things mounted on the front that prevented the hoods from tilting.

Awesome pic! I have a few Mack CL like that in the exact color and paint/graphics scheme........... but in 1/32 scale 😆 Franklin MInt diecast models.Just beautiful to see it on a real truck.

I believe the CH600 was also the set back axle tandem and the CH613 the axle forward tandem . It also seems like the CH613 were used for heavier applications like dumps and low boy tractors

Thats very nice!

Has anyone actually seen a new Autocar conventionals on the road? I have not seen one even at the numerous truck shows this summer in the NE. I also looked up to see if there were any dealers but it seems you have to contact Autocar directly
