U2450 UNIMOG 6X6 - Is it all that it's cracked up to be?!

[@karlk6860]

Hey guys I have been collecting and restoring both US and German military trucks for years and have been a Unimog owner for a lot of those years, of course only the 4x4 versions! Thanks a whole lot for sharing this video I have always loved the 6x6 versions of all trucks but have never seen this version in action, This is a very well equipped truck with the material handling crane and the tow/lift capacities on the rear, all extremely cool and HEAVY! I am now a subscriber and look very forward to seeing your next vid, thanks again for sharing!!!!!

[@Lee-in-oz]

Dan, would the 46" tyres with the beadlocks have worked better up these tracks rather than the stock ADF tyres?

[@unidanengineering]

Likely, yes. The 395/85R20 tyres would provide a larger footprint. The main thing holding this vehicle back on this track is the huge amount of weight on the back and the slippery terrain. We believe that if it was a 4x4 U1700 (i.e. less weight and different footprint) with 395's and hutchinson bead lock rims, then it would have gotten up. It just happens to be that there was a rock ledge on every one of the 6x6's axles, which certainly wasn't helping.

Does it not have a ctis on board?? A little less air pressure in the tyres may have helped or maybe even a little extra weight 🤷‍♂️

[@unidanengineering]

@mark Phillips correct it has CTIS. Dispite it not looking like it in the video. The tyres were at 1.5bar (22psi ish). If they were 395s I’d be happy to go a little lower but 365s, sharp rocks and 13500kgs 1.5bar the tyres were bagging ALOT. Slippery shale rock steps, pretty decent incline with a fresh coat of mud doesn’t agree with that much weight unfortunately. Add in the lack of power to due the the fuel blockage it just wasn’t our day. I too thought it would walk up it as we have done way bigger hills in the 4x4 mogs.

[@karipintakivi9153]

How about backing up the troublesome section at around 4:00 minute mark? Twin axles could probably have had better traction to get over the slippery rocks.

[@TheRaptor1967]

4WDing up a tight path in reverse is REALLY hard. Its almost impossible to negotiate your line because you dont have rear steer on that rig (or most rigs). The idea is good, and some off road rigs do have dual wheels up from (dual steering axels) and a single fixed at the rear. Yes, that is more effective, but its more steering, more maintenance, more things to break on the track, etc. But worth considering if you can get one. Not sure if they ever made a Unimog 6x6 in that configuration. I seem to remember seeing one in a comp truck video, but that may have been custom made.

[@karipintakivi9153]

@@TheRaptor1967 If in a tight spot where one just HAS to get through anything can be at least tried. I once was on an expedition where we rode two Russian Ural 6x6 trucks from Bishkek over Torugart pass to Kashgar, then along the Taklamakan desert to Kun Lun mountains to the foot of Ulugh Muztag mountain base camp at 5300m altitude on the Tibetan plateau. Nobody had ever been up there before us, we were 600 km from the nearest human habitation, took us 7 weeks total, Both trucks had their front axle broken along the way, rear fuel tank fell off at full speed, we were frozen in quicksand for 6 days at 4300m altitude etc etc. But we made it there and back and the 6928 meter mountain was climbed for the first time. When fooling around for a day you can turn back, but there are situations where that is not an option, and that is what these trucks are actually built for.

[@donstewart2059]

Hi would duel wheels be better on the back as one set of wheels travels on new ground on the4x4 version

[@TheRaptor1967]

Not really. Relatively wide single tires (sometimes called Super Singles) but with a heavy mud or rock tread are the go. Duals dont work well off road as stones, bricks, branches, rubbish etc get ledged between the 2 tires and do damage to both tires.

[@gregsheridan]

There are lots of vehicle that can get up there but it isn’t fair to compare a 6X6 Pinz to a 6X6 Mog as they are totally different weight classes. The Pinz has a maximum weight of 3,900kg with 1,500kg max payload. That Mog has more weight than that on each axle. A 6X6 chassis cab weighs over 7,000kg and total payload of 10,000kg. Different animals.

[@TheRaptor1967]

It will be a different animal once its stripped of all its excess baggage and turned into an overland expedition vehicle. The 6x6 and 8x8 vehicles make the ultimate expedition vehicles because of the size of the living pod that can be placed on the back. Only down side is small tight windy tracks that car size 4WD's often cut between trees and rocks.

A 6x6 doesn’t mean it’s better than a 4x4, only means more payload, besides you’re in the wrong gear, to short on wet clay will just dig in…. In the military we used 8x8 APCs, big, cumbersome but with payload ability…

[@unidanengineering]

No we haven't fitted these to any Mogs. We generally stick to the 20" rims and our preferred tyre size is the 395/85R20. We have not worked on the Acco's before. However, in regard to articulation we will be putting the 6x6 mog up on concrete articulation blocks this week to test it out.

Okay, I'll say the same thing differently, the contact patch of the tyres was too short (front to back), and the tyres were not bagged out enough to enable them the best chance to grip things. Is it possible that the side walls are so stiff that the actual contact patches are carrying a lot more than 14 PSI? One reason to get a mog would be superior puncture resistance. . I suppose that if you have bead locks, you can air down even further, to 1 PSI. My last comment is that if the tyre is the wrong shape, you have too much pressure in it, or the sidewalls are too stiff, and that that is true even no matter what your tyre gauge tells you. Stating the same thing differently, to disprove my comment, you actually need to quote me how long the contact patch is. The length of the contact patch is the only way to tell if you are aired down far enough, because lengthening the contact patch is they whole idea of airing down. Stated differently again, as Forrest Gump would say, "Over inflated is as overinflated does". This whole thing is actually a really good argument for you to encourage people to fit the narrowest tyres that they can find (unless the side walls are still too stiff or beadlocks make this factor irrelevent).
