Can anybody tell me what is going on here?

Not to say we all (me included) don't do some stupid stuff from time to time out on the trail away from prying eyes when needs, lack of knowledge or resources dictates. But its not a good idea to 'teach' that stuff to others now is it? IF thats what they were doing of course.

Seriously? You'd get under that, rigged in that fashion? Couple of tires is not going to keep that thing off your head when something lets go and that comes down.

If you have the two wheels that are currently in the air resting on supports how is it going to come down on you?
But I can't think of anything that would need doing that would require lifting it like that.

I've seen so much crazy stuff done, and done a little myself , that I could, obviously, believe that's what they were teaching. But yeah, it was probably a sarcastic caption.
I think I'll go back to the making a wish theory until someone knows otherwise. lol

The wheels in the air are in extension. You could put a couple of spares under them and there will still be air between them and the tires. When it comes down that air and the compression of the suspension is going to drop the height of the vehicle quite a lot. Even if you stack say 4 spares (assuming you have them) there is still going to be a drop from the vehicle that will most likely put it in your face at the very least. Remember you are 'working' on it so you're up close and personal to it.

Add a couple of high lifts as supports and back off the lines a little to balance the load or stack some tires and lower it onto them to help support the weight and take out some of the compression. Then it changes the dynamics what you're doing and minimizes the risk. I haven't seen any pictures of them showing anything like this but that’s not to say they did not verbalize it. Problem with saying something is that bit gets forgotten and people only (partially) remember the part you actually show them.

Also, if you are going to winch on an attached point such as that cage then cross the lines over the top so the pulling forces are working into the vehicle and not just trying to pull the cage off. On that truck a better attachment would have been to cross the lines and go round the tops of the b-pillars through the window openings. No cage to separate and the truck is sandwiched between the lines with nowhere to go as long as the lines and other rigging components hold, the winch brake doesn't slip and the pulling trucks don't move. I still wouldn't get under it unless it was also supported though.

I am not so sure. Here is another caption from a different set of photos posted by Peak10:

"A Camel Trophy veteran explaining backcountry vehicle service. The Rover was winched on an angle so it could be worked on without crawling under it. Not all repairs are done on a flat concrete surface. Some are in the mud, in the jungle, etc."

From what I have seen and read so far it just looks like they winched a truck up on 2 wheels by an attached component and then put it in a counter stress from a fixed vehicle and suggested you could now work on the underside. Hopefully somebody comes along that saw and heard the demonstration and can tell us that’s not what was going on.

I think it was static training for the revival of Joie Chitwood's Thrill Show.

You missed where I said wheels "resting" on something. In other words maybe lift it up as shown them lower it on to something, essentially like you do with jack stands. You don't work under a car supported by a jack, you only use to the jack to get it high enough to get supports under it.

IMO it's better to go over the top and attach to the chassis.

In any case, I think everyone knows this is how you should change a tire in the field.

That video was pretty funny/scary.

So in other words we're both saying the same thing. Lift it up and then lower it onto supports of some kind before working on it.....

I would agree with you on the chassis except that you're going to bend the lower part of the body pretty bad with the straps.

Sounds like.

It depends on where you attach it. or rather where the strap is. I've found I can usually rig it in such a way that the pressure is on a structural member, not that I upright that many vehicles, but I've done a few over the years.

I've typically found that when the vehicle is on its side you can't easily get to the opposing (lower) side of the chassis with a strap. The strap has to pass under the vehicle and it's not typically possible to feed it under there. Even in uneven terrain where there may be gaps and so forth it's not a good idea to be messing around under the truck trying to feed a strap through. In softer terrain or water, forget it. I like to use the opposing b-pillar if the vehicle style and the lay allows. It's fairly central to the body, still provides a rotating force and is plenty strong enough to right the truck with minimal additional damage. Sometimes the type of vehicle (pick up/soft top) or the way the truck is laying doesn't allow you to get a strap there so you go to the uppermost body or frame mount on the underside facing you. No rotational effect, less leverage due to the lower angle, more force needed and more chance of sliding initially are the tradeoffs but sometimes it's the only option.

Hypothetically (since I've never come across a situation where it made sense to me to do this in this way during normal trail or overlanding use), if you are just tipping an upright vehicle to make repairs as they are (or appear to be) demonstrating here, you could go to the opposing frame since it has rock sliders and there is less danger of damaging the lower body. On a stock truck the frame itself and the outriggers are inboard of the outer body panels with no substantial panels to rest on and the strap will bend the panels at that lower point. On different vehicles it may or may not be possible depending on the position of the frame hard points and the body panel or armor (if any) configuration. You'd have to make the call on a case by case basis, assuming you wanted to do this to begin with.

What I think we agree on is that you never want to attach to a 'bolt on' accessory such as a roof rack. On a flimsy external cage such as this one you would want to be pulling it into the truck rather than away and even then only if a better option is not available. It would appear a number of better options were available to them in this set up as pictured.

Awesome video. I lived in Arabia for sixteen years, and I never saw anything like that on the highway. There are lots of empty roads on which to attempt such stunts in Arabia. But if it goes wrong, it may go wrong big time because they may be hours away from the hospital. I admire their courage but doubt their judgment.

That 110 is Graham Jackson's. I'm confident that whatever was displayed there, he was present, and it was demonstrating a very important skill with safety at top of mind.
