Yes, a lot of people don't want to risk messing up their >$100k truck offroad.
Well, I really can't say what the market is for brand new expensive trucks that are stripped down and ready to beat up.
Well, hasn't Fiat already said the TRX days are numbered? Will they really try and one up them again? Besides, you could argue that the latest crop of EV trucks are already beating out the dinosaurs. If not now, then hybrids and EVS certainly seem to be the way forward in terms, for this contest anyway.
