Locking front and rear differentials and proper throttle control beat Toyota's crawl control any day of the week. All it's really doing is "faking" locking diffs and spinning the wheels very slowly to generate maximum traction.Whatever, I have used in my 4Runner to extract myself from a similar situation. It works and that’s what’s important. I don’t give a fuck about its software coding and I cannot say that with any confidence about a Jeep product.
This can be easily done with real locking diffs and good throttle control - with even better results.
