Possibly acquiring a M931A1. Feedback..?

[MatthewWBailey]

I'm looking at an '86 M931A1 on FB that the seller is calling a "M921A1 former tractor rig"
W/42k miles for $11k.
it's been frankensteined a bit but given the low price motivation and close location, maybe I could enter 6x6 world.
But With the older Nhc250, is this a waste of time or workable machine? It would be a parade queen but certainly OHV mud smashing too. I'd have to acquire a real 900 series cargo bed or fab something. Any advice is golden..

It’s a rolling identity crisis!!! Fortunately nothing a cutting torch can’t fix!

I prefer the NH250 to the 8.3. I've owned bunches of both, and currently own both....

Did he extend the frame too? That’s longer than a 931.

Yes his description says
"1986 M921 originally a tractor rig
NH250 Non-turbo
Allison 5 speed transmission
Professional frame extension and trailer bed added. Bed is set up with two aluminum benches for passenger seating.
All brake diaphragms professionally replaced. Starts, drives and stops amazing.
7- Goodyear 14X20 tires
8- Hemet wheels
All fluids changed when purchased. Both rv 5th wheel hitch and trailer receiver mounted in rear. Will need: front axle boots, fuel gauge works intermittently, windshield wiper valve replacement "

Those aren't HEMTT rims.

14.00s are getting scarce. I'd choose 16.00s or 395's, and those look like 395s.

Changing brake diaphragms is pretty trivial.

The boots are no big deal.

That's an M105 bed.

I like truck tractors with a 12' bed and truck tractor length frame. They look proportional like that. This one looks awkward.

Is it in Albuquerque, NM? It looks like my friends truck

 

[M813rc]

I agree with 98G on the engine. I have trucks with both and like them both.

I've run my M813 with the NHC250 in it for 20 years and had no problems with it.

Cheers

What are your plans for the truck?

If you just want to drive it as is, it looks like you're good to go with the minor fixes described above.

Otherwise, you've bought in to a lot of work to get the truck back to a semblance of originality. In the haze of infatuation and apparent cheap price, that work almost always takes much more time and money than what you're thinking.

Lol.. It doesn't really matter where it is does it? It's your friend's truck for sure. There can't be more than one of those in existence.

I'll even bet the frame stretch was done by Durkin.

 

[fsearls92]

Haha, I guess that is true. Just wasn’t 100% sure as I haven’t seen the truck in about a decade, but know they still own it. It is a well taken care of truck, I have ridden in it and serviced it myself. If I remember correctly they bolted on the frame extension.

The front rim is definitely a FMTV/LMTV and I also think they are 395's on the front.
Pic angle makes it look like the rear could be 14's. Doesn't look the same height.
Probably someone not informed fully but not trying to deceive. YMMV
Truck is cool and definitely worth considering. I would consider finding a bed to replace the M105 trailer bed.
The rear add on frame is growing on me and could be a platform on the rear of a new bed. I also like the steps in it.

My .012 is go for it if it drives well with no leaks or issues on a test drive.

I was thinking that. Seems like I'll be doing a month of steel work to bring the rest back up to looking good.

Here's other pics of the wheels. Seems like tire musical chairs

 

[MatthewWBailey]

There's an A2 local I'm going to go look at tomorrow instead. Close enough to test drive.

I saw this unit this Sunday. Only 16.9k miles. New tires. Fired right up after 6months of sitting. He's got a 24v to 12v converter on the back to run generic 5th wheel trailers. All in All a sweet rig. Luckily I don't have 15k to give him bc this is an addictive looking vehicle in person. Someone buy it please before I have to go back to rehab.
