Scripted reality tv crap and a very poor representation of the off road community is what I think the show is.
I have had to widen a few trails before, the trees in that trail where way too big in diameter to be pushed over by anything on that show. Wasn't the land cruiser guys right behind the Jeep on the trail helping them cut and move trees? I think the jeep and land cruiser guys just drove over the downed trees in the middle of the trail that they could and cut the ones that they coundn't drive over. The rover guy was butt hurt because didn't bring enough 4x4 to be able to drive over them to it and had to cut more of the downed trees, costing him time.
You don't talk to people the way the Rover guy did without there being bad consequences.
About 30 seconds into the Rover guys rant and I would have given him the opportunity to STFU or get air lifted to the hospital.
