Twas the same for Four Wheelers Tough Truck Challenge. Lots of 'what's going to sell magazines' rather than a full open competition. Supposedly, readers got to choose the participants, but rather it was FW that did this. This lasted for several years. Supposedly, this has changed. To what extent, couldn't tell you.
I have same look at the mags video on last years UC. We'll see if it's like it again this year.
