Towing HMMVW with HMMWV.

[jeffy777]

I have got someone else to join the community of insanity and they won a 1989 6.2 HMMWV. He has a trailer 83" wide trailer and a modern Chevy pickup. I thought it would be fun to go pick up the HMMWV with a HMMWV(1987 6.2 HMMWV). It is about 40 miles round trip. What do you guys think?

Easy tow

Send us some pics, that should be an easy pull

Sorry to be the party pooper but I dont think it would be a good idea at all. These trucks are woefully under powered as is and you're looking at adding another say 7-8k pounds to it, not to mention the brakes. The military only rated these to tow 3.5k pounds.

Hmmvws are 5200 lbs. A 3/4 ton truck would be best.

So, just asking, if a fully loaded Humvee comes in at 20K and can run around with all of that extra weight, and a de militerized is about 5,200, can't you apply the lost of the 15k to pull another vehicle ?
Again, just asking...

His 1986 hmmwv is far different than the new up-armored ones. They have turbo motors, bigger brakes, stronger frame and suspension, and a stronger drive line.

5200 lbs is like towing a taho. Having trailer brakes would be nice. On these that are being sold I dont think they are rated for 20k. I tow tow autos all day eveyday. I expected mine to tow heavy, but it did not. Felt like 4k lbs.

The Hmmwv weighs 5200 but a trailer big enough to hold it probably weighs another 2k. Thats 7200 on a truck rated to tow 3500.

Sort of correct.

Good luck with the 83" wide trailer. Mine measures 85" sidewall to sidewall.

Flat tow with a tow bar? Or on a trailer? I towed home one with my 1/2 ton Chevy pickup (6 cyl, 2wd) and it was not even noticeable behind me. That is with proper hitch equipment and trailer brakes. Flat towing with a tow bar, what, 20 miles? Yeah that would be fairly easy also. Putting a trailer on the HMMWV and trailering it with a HMMWV, nope, no way.

 

[jeffy777]

So ... I was not thinking. I should have read the -10 on the subject. The HMMWV can probably pull it just fine the Pintle is rated for less than 3400lb. I am not worried about the breaks and such. It would be twenty miles and I would take it easy. As for the trailer width, I think you will find it is 82" tire to tire(outside of tires) and 85" is the width of the body. I have read several times on SS people say 82 inches on width for trailing.

So the answer is no. No HMMWV pulling HMMWV for me at this time. Thanks!

Pintle is not the problem. It is probably in spec.

It is the original curved bumper- noway.

MWO replacement flat upgraded bumper- still no way on weight.

MWO airlift reinforced plate bumper still only 4200lb- out of your parameters.

Send me a pic of a 20,000# humvee! Where did you hear that? The heaviest I see at the moment is the m1167 at 10,800# curb weight. You thought it had 15,000 pounds of armor?

I used my 2003 4.7liter [NOT A HEMI ENGINE] Durango to pull a 5000+lb Diesel Landcruiser 2200 miles twice. I did NOT use a flatbed trailer, but my vehicles both had titles and insurance. I had a brake assist, and it was easy.

20-40 miles at 20-45 MPH in a HMMWV pulling another Hummer? I see no major issue IMHO (others obviously disagree).

Maybe not to spec, but given military overdesign, I would feel comfortable driving SLOWLY, or driving with a Readybrake brake assist device. My dad helped design and test US tanks. Our military overdesigns EVERYTHING!!! (That is why the whole titling issue over street worthiness annoys me no end. - but I digress.)

I used the device attached below, called a Readybrake. As you slow it mechanically activates the brakes of the car behind. It worked amazingly well. One of the few purchases I made that worked better than advertised.

Yes, others will disagree. I can speak to the effectiveness of a flat tow of a 5000+lb vehicle with a 2003 4.7 liter Durango over 2200 miles without issue using a Readybrake. The drive was smooth and at 50-60MPH the brake activation allowed comfortable safe deceleration.

YMMV,

I did install the airlift bumper with the reinforcement, I think that I have 26 1/2 grade 8 bolt holding it to the back of the truck, I am short of the 2 shorter brackets going to the pintle , you would think that the bumper could pull anything, guess not.
By the way , if someone has the shorter brackets, that go to the pintle, let me know

 

[LouWon]

Yep, my bad, I was certain that they would be bullet proof in order to protect our troops. The way I see it there's never enough protection for them.

The current production Expanded Capacity Vehicle (ECV) model M1113 has a payload of 5,100 lbs. That is over 2 ½ tons, or very nearly the M1113's own weight of 6,400 lbs

I used to flat tow them all the time in the army, drop the t-case in natural and go. remember you will need extra room to stop, and don't use the double eared towbar attachments, as they wont have enough down ward articulation. they can pick up the rear wheels, and cause you to loose control. doing it this way will cut 2000 pounds of the towed load.

 

[MaverickH1]

We often talk about the 92 and 93 Hummer H1 is nearly identical to the HMMWV. The attached says it can tow 9,000 lbs. Keep in mind, the military rates it for off-road towing weights, hence the lower number. And the bumpers are different. Just my observations...
