    OK, I see that CK5 is going to start selling some angle guages. What Im curious to know is... at what angle is the average 'rollover point'? I know that every vehicle has its own 'breakover' point, depending on springs, tires, load, but if I had one of these on my dash, where would I start to really sweat? Barring any tree roots in the uphill rut, or any gopher holes in the downhill rut, just with a truck on a flat deck, that was tipping over, what approx. angle would a unloaded fullsize K5 want to roll?
    Just wondering... I know some have seen it.

    A couple of us in my club were thinking about testing this. We wanted to lift the side of the truck with a forklift and have a strap tied to the cage to hold it with another truck, so when it just barely started to shift the weight over, we could catch it and let it back down. The only problem is that no one wants to volunteer their rig!! [​IMG]

    An unmoving rig w/ no momentum will go farther over before the point of no return, than one that is moving.

    Yeah I know, but it will still be a decent approximation. We also thought about using our RTI ramp since that would allow the truck to be moving. It would simulate trail conditions better too, since most of the roll overs you see are while someone is trying to get up a cliff or boulder and the truck is flexed out all the way.

    I think 45 degrees is around the max (one of the reasons the gage only goes up that far) I have had mine up to 35 degrees and I can say it was not that fun.

    Awesome pic. Thats 35 degrees huh.... I think I have been close to that, but it always seems waaaay more when youre in the chair! I know there are a million variables to this question, but I was just curious if anyone had an approximation.
    Thanks

    There is a video tape of mine about going over (daylight onder both Passenger side tires I have been told. I have not seen the tape. Just what I was told when I got to the top. I was being winched up guard rail and they say the winch caught up and was the only reason why I didn't go over. I'll try to measure it when I see the tape in a few day's

    Pics just don't do justice, do they? And I have a question... I have seen many times where a rig is at a steep angle like that and someone is beside it supporting it. Well, if the rig started to go, do you think he could really hold it?!? Or do you think he would turn tail and run like the wind?!?

    Yeah, it doesn't look as bad as it was in the pic, but you would be surprised what one person can do when a rig is at that balance point. If it started to go over he would have gotten out of the way, he was at the rear corner. What made it scary was that it had snowed off and on during the day making everything very slick and as I drove forward it would slip from time to time on the iregularties of the rocks, major pucker factor.

    When I rolled I was sideways on a hill thats close to 70 degrees in some areas. I didnt rolloever till I lost momentum. I have it on video just need to figure out how to put it on the computer.
