. Yes you do have to point the truck to the left to combat the off-camber situation. The problem is, not shown in this video, is that you'll be facing your truck to a drop to the edge . You have a small patch where you will be dropping off your left front, and once you're planted at the bottom then you can start straightening back to the track. I think this is enough to make folks take a straighter line as it looks "safer". Couple that with a natural reaction to hit the brakes and you got a reciper for a rollover. This truck in the vid didn't seem to have much front flex at all so i think that compounded the situation.
You want both hands on the wheel all the time. First is so you always have a firm hold if the wheel jerks but also because in the the case of a flop or roll you want to avoid your arms getting flung out of the window and broken or crushed. Like they say at the amusement park, always keep hands and feet inside the vehicle. Also I was taught to keep your thumbs on the outside because if you do roll or the wheel gets spun you don't want to break 'em.

Honestly, I have an inclinometer on my dash and an app. I have never used them while in a situation. If you are paying attention to the meter then you are not paying attention to your driving. It has made for fun conversations after the obstacle if you had a passenger looking at it. I have been in the spot referenced in this thread on Black Bear and it is very deceiving. I have a RTT and have always felt the pucker factor long before the vehicle was in danger.
Inclinometers are bling for passengers. As someone said already, if you're watching it - you're not watching the trail. Reactions are everything and they have to be quick, decisive and correct. In these 2 videos, 2 very different situations, but both had inexperienced drivers - well, no one really wants to experience a rollover with their rig. In the 1st video, (which by the way is a bad example for this thread, because the rig did not have a RTT. Anyway,) the rookie spotter needed to tell the driver, once he lost momentum and couldn't continue uphill, to crank his wheels hard left to get the rig in a straight uphill posture as he was backing up. You could barely tell from the camera angle, but the path had a slight sidehill bias to it. Not an easy climb and worse for top heavy (read RTT equipped) vehicles. Biggest rule on climbing or descending is straight up or down and keep that posture as much as possible. If you are coming off of moving sidehill, choose downhill. Reason being that you want the natural tendancy of cornering forces to work for you and not against you. IF you turn uphill, the cornering force will be aided by gravity to cause you to roll the rig. So if you MUST go uphill from a sidehill posture, slow your rig to walking speed or less, before turning. In the 2nd video, the angle and distance makes it difficult to analyse. Driver's track looked like, a poor choice because he had downhill wheels (driver's or left side)in a slight depression or erosion channel which made it more of a sidehill bias than necessary. Almost looks like driver's side front wheel either hit an obstacle or dropped into a pothole because you could see the rig stop and the rear end shift to the left (downhill) as it rolled over and driver was probably hard on the brakes. Good that he was crawling and just went on his side, because I bet that hill was steeper than it looked in the video.
Didn't mean any disrespect. I think both videos show how easy it is to roll over when one doesn't keep their wits about them. And even then - top heavy, or hauling with sizeable load on top, means you got to watch things even closer. But, I think it would be wise to avoid extreme trails &/or obstacles with a RTT. I just pulled my RTT and awning off my 80 for a TLCA event and it shouldn't surprise me how much weight was up there - 'cause I put it up there...lol. But it did
