1-1/4 ton military jeep pickup

[brushawg]

I know they are out there have seen some on ebay, but can find any infomation on the difference between them and a J20. Can someone help me out.
I'm wanting to build a super heavy duty dually for towing.
thanks in advance
Also I'm not talking about a m715 but a regular fsj truck. Know we had some in the U.S.A.F. FD as brush trucks!

M715:
Relatively weak, insanely low geared axles. Underpowered and delicate engine for towing. Transfer case overheats at highway speeds.

J20: Typically an AMC V8, decent axles. Overall, more modern and confortable vehicle. Parts are much easier to find.

[mdill]

Goverment liqidation did have something that did have a 715 (??) in it's discription, that was a later model Jeep truck (80 ish ??) a long time ago,
not sure if this was something other than a regular J-20.
Maybe AMG made some USAF only variants with bigger axles (??)

There are strengthening frame parts (brackets) ...that fit our J Trucks.

Find part numbers.... Only in military parts books. :D

You ever driven an M715? you'd have to do a lot of upgrades to make it a DD/tow rig. Just one of which is power steering or at least a spinach dispenser in the cab cause w/o PS it's a short time as a DD before you end up with forearms like popeye Not a fun vehicle to drive in traffic. If'n were me I'd go J-20.

All depends on what you want in your tow rig. All of the comments are true but how many of us have done engine/transmission/axle swaps in our rigs? The M715 has a much stronger frame than a J20 on a slightly shorter wheelbase. All of its short coming can be addressed and some people have even swapped the M715 body onto modern frames. Where else are you going to find a convertible tow rig? For mine I just did the upgrades: 6.2 diesel/NV4500/divorced 205/GM Dana 60 front/14 bolt rear/disc brakes all around/5.13 gears/SOA to fit the 42" Swampers/power steering/hydroboost and more.

Is it a modern tow rig or daily drive? No, on both accounts. But boy is it fun to drive and it gets lots of attention where ever it goes. I may add AC at some point via Vintage Air but for now it is a ragtop. Besides, I have always been a bikini and topless fan.:D

There are Export only HD brackets for the cross member mount, a crossmember for the motor mounts and a front radiator cross brace,
was thinking of adding them (well look at the parts book picture(s) and mimic them), in the normal (non-mill) parts books.
Anybody know of a source for the millitary books?

Would love to see some part numbers and pics :) My J3000 M715 clone wannabe could use some of that.

I love J trucks, but M715's look soooooooo much cooler stock that most J trucks will built. :thumbsup:

[mdill]

M715's are cool, but to make a driver, there is not much from the drivetrain that is a keeper, pull it all from axles to the engine fan and
all in between, then swap in something that can be run without killing
the driver.

[Songman]

They do look good though. No question about that.

Yes ! that is the picture of the beat to crap one that was on the US Government Liquidation site awhile back, and the big lot of Swedish (??) J-trucks. (If my pockets were real deep, that lot would be cool)
There is always the KIA M715's that are more modern and go 1-1/4+ tons.

I haven't really heard of the 6.2L diesel referred to as an upgrade :confused:

Most consider it a boat anchor missing the chain ;)

It was a decent enough engine for the military to make extensive use of them. I drove enough trucks with them and never had a problem with reliability or with power output.

[Chumley360]

Grantshire's truck is awesome, IMHO.

But to the point I like the way my M rides. Sure it's stiff and bouncy, unless there's 2000lbs or so in the bed, but it's a truck. You should ride in some of the 1-1.5 ton service trucks we've got on base. They're Civvy models, but aside from the AC and heat, they ride just as, umm....good:eek: Just get some good seats and keep the tires around 40-45psi, unless it's loaded, and it's not too bad. If you'd like a truck to ride like a Caddi, get a Chevy. They've spent years designing a truck that rides like a car. I do have to agree that the drivetrain is weak and under powered, by today's standards. But honestly what 40+ year old vehicle isn't?

[AMC-J/20]

True that true that . . . But 40+ years later they are still getting the job done what new truck thats around you now that'll be around in 40+ years ? :confused: ?

Must not be in a hurry ? . . .

I have a 95' K2500 with 6.5-T, 4L80E, 4.10's, and factory tires, Its actually got a few power adder's . . .

I put an ATV in the bed, and hitch up the trailer with 2 more ATV's on it and the truck is doggy sluggish accelerating and once finally up to speed its straining awfully hard to maintain speed :o

It loses it's @ZZ in hill's it lose 15-25mph down shifts yet still top's the hill running 8-12mph slower then when it entered it :(

Now considering the 6.2 is rated for 135hp & 240tq and the 6.5-T was rated for 190hp & 380tq I can't imagine the 6.2 towing any better :confused:

Is the 6.2 more reliable then the the 6.5-T sure :rolleyes: But i would think of them of an upgrade . . . IMO :thumbsup:

A typical load for the CUCV's that we operated was about 2700 lbs, along with about an 8000lb trailer in tow. Military trucks, military convoy, so we avg about 50 to 55 mph (if we were lucky). Outside of a convoy, we could run at around 65 or so with no trouble.

A typical run for us was north from Dallas to OKC. No mountains, but some respectable rises around Davis, OK. I don't ever recall it being an issue from a power stand point. Typical loaded weight (and this was around 1990, using 1985 vintage trucks) was around 8000 lbs on avg. The trucks only failing was the 15 gal fuel tank.

Not sure what to say about your truck... :(

These are for the M15, don't see anything about being export only:

Crossmember, engine, rear support assembly 65909-943873
Extension, rear crossmember, left 65909-946021
Extension, rear crossmember, right 65909-946020

Extensions to rear crossmember, frame assembly
65909-943863
65909-946564

Anyone see this on the past few weeks of xtreme http://www.powerblocktv.com/site3/index.php/xtreme4x4-episodes?ep_num=XT2010-07&ep_sea=1001

http://www.powerblocktv.com/img/Episode_Images/XT2010-07.jpg

now that is the best tow rig ever. They built the bed for their suzuki to fit in . Has air bags to drop the rear to drive right in.

The CUCV's all had 4.56 gear's running the same 7.50-16 & 235/85R16 tires i am on my truck only i have 4.10's with the 4spd auto . . .

The only 6.2L CUCV of that are that didn't have the 4.56's was the blazer it got 3.08's . . .

I'm sure with 4.56's my truck would tow better to much better but it wouldn't be engine power it would be all gear ;)

But i have though about dropping my 4.10's for the 4.56's and using the CUCV speed sender to correct my speedo :thumbsup:

Mike Yes those are the ones I've been talking about. Guess the governm,ent surplus is where I will have to check. Really would like to know what made a 1-1/4 ton though

[suzq044]

I would love to get my hands on an m725.. that would be an awesome camper :D

PS - go here [LINK] (http://www.jeeptruck.com/sale/sale.html) PLENTY of M715.

[Grantshire]

It is all in what you are looking for. The 6.2 is a great upgrade from the stock engine and much prefered to most V8 gas engines I have seen swapped into these truck. I have a good friend that has a BB 454 in his with a TH400 and mine has just as much power rowing through the gears.

My reasons for going with the 6.2 are several: engines are dirt cheap; parts easy to come by and cheap; decent power (get a military engine - emission exempt); very nice fuel economy; and simple to work on. I would not go with the 6.5 turbo. If you want more power swap in a 4BT or 6 BT. It is an expensive swap but OMG, do they have power! Bottomline - go diesel for power and economy. :drivin:

There were AM 715's & AM 720's These were modern versions of the m's built by AM general,they had civvy fenders,&the 720's had a civvy bed.Maybe that's you ran in the U.S.A.F. Zack had a chassis to one behind his shop.
