Maxidyne Posted May 4, 2020 Share Posted May 4, 2020 Probably not Postal Service, they had Maxidynes in their later MBs and naturally aspirated 673s with a 10 speed in the earlier ones. A USPS MB would also probably have the trailer raising "ramps" on the rear of the frame. BTW, saw a couple new MB tandems in Air Force colors and headed to the Air Force Reserve at the local Mack dealer back in '77, they looked to be the same spec as the USPS MBs except different color and markings. That was before my time at the Postal Service though, so I may have missed a few variants...

When the Mack museum reopens I will request info from them. Unless the pick up ramps had been welded to the frame of the post office trucks they may have been removed there are extra holes back there indicating that there was formerly ramps that had been unbolted and removed.

Quickfarms Posted May 5, 2020 Share Posted May 5, 2020 That looks like a military foil tag The registration number 77B-1165 appears to be Air Force 77 is the year it was procured, ordered. B indicates Commercial General Purpose 1165 indicates that it was the 1165 vehicle in the B class that was ordered in 1977 The blue paint is probably air force strata blue FS 15045 2 Quote Link to comment https://www.bigmacktrucks.com/topic/62347-1978-mb611/#findComment-450418 Share on other sites More sharing options...
Maxidyne Posted May 5, 2020 Share Posted May 5, 2020 The Postal Service trucks had a similar supplemental ID plate, could very well be an Air Force truck which is pretty much the same spec. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/62347-1978-mb611/#findComment-450421 Share on other sites More sharing options...

storkmack Posted May 5, 2020 Share Posted May 5, 2020 This is crazy, I was bidding on this truck awhile back. Then to see you post pics of it that show that it ended up with a mutual acquaintance in our neighborhood. Must be something in the water out here.

kscarbel2 Posted May 5, 2020 Share Posted May 5, 2020 The U.S. Navy also operated tandem axle MB611s, moving food from their warehouses to the base commissaries.
