The guy that bought the Bronco commissioned them to build it. He started Twin Peaks (a hooters spinoff in the Dallas area, I actually like it better), that's why the Bronco had a Lumberjack theme.
During the initial test drive of the Bronco, where Richard usually dogs on the rides, he tore both axles out from underneath it. They had one of the big Bronco guys in the Dallas area rebuild them.
I actually like the show. Richard is obviously over the top but I think Aaron is a very talented builder.
As for Dennis and Collins Brothers, he gets a bad rap for his prices because he knows that he has product that people want and need therefore he charges for them. I think most of the people that are bitter with Collins Bros are the ones that have wanted something they have had but didnt want to fork over the money. No one that really knows jeeps probably wouldn't buy one of his jeeps so that's why he doesn't advertise and forums like this. He goes after the people that don't want to turn a wrench but has the money to buy one done. Plus he does in house financing. May seem shady to some but I see it as he has found a niche that has turned into a large financial gain for him.
