And I also want to say that I do feel that there is a place in the market for the IWE delete, those that run crazy hard in 4wd or mud a lot can definitely benifit from it. But at the same time, I also would not want a daily driver with that setup because of the previously mentioned points.
But what about those of us who do run crazy hard on trips yet do drive the truck everyday? Seriously I would love to do something like this if it would help guarantee that when the knob is turned to 4x4 it will actually go into 4x4 every time. Almost every event I have been to someone suffers a failure of the stock system. Quite often that is the end of their trip too. Last thing I want whether on a full blown off road excursion or something close to home is to need 4x4 and not have it work. This is the reason I would love to have a replacement/upgrade to this system that makes it reliable. Loss of a little mpg isn't a deal breaker. However wearing out everything and creating other problems would be a deal killer.
