Where is this label (part # 4MR2625M) place on a RW 613? Probably on the driver's door jam below the latch? 2" wide x 4" tall

The first Mack in Australia was imported from the US in 1919 (AC). That truck still exists in the Champion collection. Mack started building trucks in Australia in 1963 and still continues today. 2019 was the 100th year celebration by Mack Trucks Australia.

It belongs to Mike and Kelly Osborne, Osborne Trucking, near Riverton, Wyoming. Their business and trucks have been featured in Wheels of Time magazine twice. The truck is V8 powered. I think the bulldozer is a 36A D8. Mike uses that for snow plowing in his driveway and removing cattle guards. The Freedom Series trucks have been discussed in many threads on this forum. Do a search. It was a special edition (<200 produced) of MH and RW Mack trucks in 1986/ 1987 with a 3 year 300,000 mile warranty that offered "complete Freedom" from repair cost. All trucks left Allentown with the Phantom grey paint with red trim and the statue of liberty graphics. "War Dog" is much more of an expert on things Osborne than I am. This is the decal on the hood:

Mike- I sent you a private message.

Vlad- that is the cab suspension (?) that was used with a sleeper compartment - at least on the early trucks. From the records at the Archives at the Mack Truck Historical Museum: Freedom Series engines: (these numbers don't add up to the total production due to some missing build sheets) E6 350 131 E9 500 14 E9 450 8 E9 400 5 All of the Magnum Series left Allentown with one of the 3 E 9 engines.

The build sheets for the SuperLiner II Magnum (186) trucks all list "Air Suspended Cab Mounting" as part of the standard package. On all trucks equipped with either size (36" or 60") sleepers, that item is either lined out or marked "deleted". My truck had the 2 shock absorbers installed as in the picture above and a block of rubber (might as well have been a 2 X 6) mounted where the air bag and control would have been placed. All of the sleepers I have seen are ridged mounted - just rubber bushings on 6 steel brackets. I replaced the rubber block on my truck cab with a Mack air bag and control rods and used a modern, flexible cab seal. Seems to work just fine.

The collection does include the Australian limited editions (4). These trucks have been added in the last 4 years. The Freedom trucks do have the correct Statue of Liberty decal - just hard to see.

If you think any of these big shows are going on as planned, I have some real nice beach front property in Colorado you need to buy. May not even be any shows in 2021. Grab the reins - we are all going for a ride.

My input deleted - way too much bad information in this post.

An R800 just out of the Champion shop in Queensland -

Issue is resolved. There is a pressure switch outboard and forward from the treadle/ foot pedal valve. Corrosion from Pennsylvania salt, calcium, beet juice and other evil chemicals. Required removal of primary fuel filter and fuel lines, 3 air lines to access. Thanks for input.

Thanks for the response. This apparently is set up differently. There are two 14 post terminal strips on the left side of the firewall under the hood. On the inner strip posts 4, 5, and 6 are stop, tail and turn signals for the truck - they all work on the truck. On the same strip posts 7, 8, 9, 11, 12, 13, and 14 go to a 7 wire trailer cable that goes to a junction box on the back of the sleeper and then to the trailer plug. #14 is for the trailer stop lights and it goes somewhere to get its voltage- it shows zero voltage from the foot valve, 12 volts from either the yellow or blue air valves. There are no electrical connections coming out of the foot pedal treadle air valve.

I have no trailer brake lights from the foot pedal. Normal brake lights on the trailer with the maxi brake (yellow) button and the service brake (blue) button. Truck brake lights work normally from both foot pedal and both buttons. The issue shows up at both the trailer plug and the wiring terminal strip on the left hand side of the firewall (terminal # 14). A jumper from terminal # 6 to terminal # 14 and everything is ok. The wiring diagram shows a "trailer stop lamp sw" - feeding to terminal 14. Where is that switch located? Is it part of the service brake (blue) dash button?
