Red Dot makes sleeper A/C units that Mack used in their sleepers,

Anything made by man can be rebuilt or remade by man esp if he has access to a machine shop to do so! I'm betting you'll come up with a viable solution.

They were fairly popular with business buyers, where utility and MPG were the driving concerns. Not popular with the "macho" duelly pick-up crowd, that wanted to drive everywhere with 6 MPG. They were never "cheap" even used, they commanded some bucks at least when I was looking at them. A housing contractor I knew was looking for a truck for his son for the business vehicle, I suggested an NPR and the son had a fit, he wanted a Duelly pick-up and that is what they ended up with, but the NPR would have served the needs better and cost less to run.

long way to go!

The why, may have been someones "why not?" and then they got the answer after they built it.

I tried to blow up the pic and look and the coupler but couldn't see it clearly. I thought it looked like a plain coupler,but you might be right, and it has someway to transfer load (plate at bottom/top) like the jockey does.

??? I agree, no load on the drives. I don't think you can transfer much if any vertical load via the coupling knuckle. I've seen that company (Brant ??) that had Western Star high rail trucks, but they were much more purpose built. May be it was used to keep company drivers from "going off the rails"!😃 EDIT: may be the company name was "Brandt"?

You'll have to learn to shift all over again, if it is anything like when I did my cabover. Everything tightened up and changed the arm movements needed.

Cables are generally sourced from "universal" cables that can be had with one or both ends that match up to what yours look like. Ones that have an adjuster in the middle of the cable run, you have to re-use the cable sheath and run new wire though, but those aren't that common.

No answer to the exact question, but more often than not, the ring gear will be damaged also. Take a good look all the way around the ring gear before replacing the starter.

1-4-8-12 are for 2spd axle or other things like trans temp etc depending on how the truck is equipped.

Ok, looking on my 1973 wiring it shows a 12 terminal Jct block wired like this: terminal number: 2--trailer LT 6-trailer brake light 9-trailer RT 3- trailer tail 5- trailer marker 11- truck rh stop/turn 7- truck LH stop/turn truck tail is also connected to terminal 3 10- back-up lights on truck

Thanks, it looks like it has 12 terminals so that would be enough. I can see a numbering system on the block, so it would be worth your time to write down which number goes to what function to make your life easier in the future. Looks like you have some abraded wires there and there is some rust and may be some evidence of heat on some terminals. There should be 2 wires for each side turn signal, one brake feed that is independant of the combo brake/turn for the truck chassie, reverse , 2 marker/tail feeds, and an aux line for the center pin on the 7way. That adds up to nine if I can still count on my fingers. I see 11 terminals in use.

It can't in my book!!

If your going to own a "classic" then you are going to have to get good at scrounging/finding stuff that that parts houses say "it doesn't exist" or they don't make that any more. A decade or so ago, finding 8.25x 20" tires was easy, bias or radial no problem. Now there are a few mfg that make that size, but they are available. If you want to find a unicorn, try finding a 8.5x 20! I have some and have never even found the spec's let alone a mfg that still make them. 24"rubber has many advantages, that made them popular in other parts of the world, they carry more weight (something that our axle weight limits can't generally take advantage of) they have fewer rev/mile which makes them heat up less and age slowly, and they allow room for bigger brakes than the smaller sizes. A few years ago I saw a new side dump trailer on its way from the Mfg to the 1st owner. I had hub pilot 24" tube types on the trailer. I assume it was going to be use for off road work at a mine or some kind. They are still out there.

Understand, when you do, you will loose road speed as well, 24" rubber is larger in diameter and has fewer Revs per Mile than 24.5" rubber. I thought you said a crane operator had some on their equipment? Here 24" is scarce but obtainable.

We've been over this, time and time again. There is no "tubeless" 24" truck tire. There is no tubeless replacement for 24" tube type tires. There are Mfg in the far east that make tube type 24" tires. Cruiseliners tire shop is mistaken, they don't want to admit it, but if you look at the MFG tire catalog for the tire they claim to be "tubeless" RIGHT IN THE CATALOG it is listed as a TT or TUBE TYPE! I'm sorry to get so adamant about it, but it is right there in black and white from the mfg of the tires. To my knowledge, there isn't nor has there ever been a tubeless 24" truck tire in the sizes we are talking about The reason tubeless tire are "half sizes" I.E. 22.5" and 24.5" is because there has to be a "gutter" or drop center in the rim base so the tire can be fitted over the one piece rim. Without that drop center it would be impossible to mount a tire, you can not "stretch" the tire over the rim, there must be a smaller section of the rim base to provide the "slack" , so the edge of the bead can be worked over the edge of the rim.That make the center of the rim smaller or the same size at the center as the tube type it replaces. so a 22.5 rim measures the same at the drop center as a 20"flat based rim, same for the other tubeless replacements. a 15" TT trailer tire can be replaced by a 17.5" tubeless, a 20" TT tire can be replaced by a 22.5 tubeless, and a 22" TT truck tire can be replaced by a 24.5. THERE IS NO 26.5" tire to replace a 24"TT So for the last time, if you want to replace 22" and I can see why, then 24.5 is the answer if you want to replace 24" then you need to get another 24" and use a tube! For the people with 24" rubber, I am no longer going to answer, I have stated what I know time and time again, and the question keeps coming up with hand wringing and hopes for a unicorn that doesn't exist.

Ok, I'm trying to wrap my mind around what you are saying. SO is there separate wires in the box for back-up, stop and turn combo for left rear truck, and stop and turn combo for right rear truck plus tail, and separate turn and brake for the trailer 7 wire? Seams like too much for a single JCT box. Trailer turn (7 wire) are connected to the FRONT turn signals on the truck, while being supplied a brake light feed that is independent of the combo feed from the turn signal/brake combo the truck uses. That is a lot to stuff in a Jct box.

No doubt that 24.5's will be a whole lot easier to find. I always carried a spare tire mounted on a rims, so no real problems, if you don't then you want easily available.

Is that JCT box for the 7 wire trailer or for the truck tail lights? I can see the 7 wire being in the cab but the lights on the rear of the truck generally run down the frame rail. You need wires for reverse lights that will not be on the 7 wire trailer cable, plus they generally only have two lights on the rear of the truck, so need a different feed from the turnsignal switch to incorporate the brake light function as well.

You used to be able to get bias tubeless, bias and radial are ply construction, tube or tubeless is another matter.You can and I do have tube type radials, and I have a bias tubeless. 22" is more of a problem than either bias, radial tube. the 22" size is hard to find, for that reason alone I would say go 24.4 tubeless. 20" used to be a lot easier to find, and a lot more choices when you did find them. I guess they are getting harder now.

Beats 6 mpg on a 6.9 Ford. Heck the L-10 semi would get 6. Just needs to get you where you needed to go. The less you spend getting to and from the job, the more that ends up in your pocket!

I put an engine in one of those, it had an exhaust brake (didn't work at the time and the owner didn't want to fix). What kind of fuel usage did the 4 cyl diesel give? I thought they would make a better service truck than the Superduty Fords I had.

Just wait, it will happen so often you loose the embarrassment. Remember "A mind is a terrible thing to loose"
