The intention was not to compare the two trucks. The intent was to explore the usefulness of the 4 ETS system. It is no secret that I am a skeptic when it comes to trusting such a system in off-road situations. The mention of the ML was a bit of a poke:p at the folks who think 4 ETS is the equal of, or superior to, a set of mechanical differential locks. The reason I tried this test was to see for myself how well it works. I am open minded enough to admit it, if indeed the system proves effective when applied to my needs. So far I do not see any merits. There may be a problem with the system on my truck. When I get some time again I will test it a little more. If it still does not function as advertised I will have the dealer look at it. And yes, I know exactly how it is supposed to behave. It is not working as advertised, that is what we are exploring here.

Gilly, I am not concerned that the dealer will deny any warranty coverage based on how I use the truck. I am a little curious to see how they would replicate the problem. This is the kind of thing I would like to be involved in. I have a good relationship with the shop foreman at the dealer. The problem is, the dealer is 150 miles from home.

I also never reached the point where I had two wheels off of the ground. I managed to get far enough to raise the one wheel. At that point, the one wheel spinning halted progress.

My next round of testing will consist of using a little more throttle to determine if I had actually reached the intervention threshold. I will also try lifting different wheels to see if I may just have a bad wheels speed sensor on one corner causing a failure. I will post the further results.

Regarding the MOG as the ultimate off-roader. Yes, it is certainly more capable than about anything off-road. Getting it to an off-road venue is a different set of issues. The MOG is rude and crude. Mine has a top speed of 53mph, and REQUIRES ear plugs at that speed. The cabin is cramped, do not plan on a passenger exceeding 5'2" in hieght, that side is even more cramped. Point being, the MOG is a very specialized tool, the G is far more versitile offering excellent off and on road qualities.
