I personally don't like the look, but I can see why it would sell. There are alot of people that like trucks fixed up but do not know how to do it for them selves. On this site alone, over half the people have their gauges, E-brakes, and everything else they want added done by someone else. They do not feel comfortable doing the work them selves, so they have it done. They are usually also the very first ones to complain about something, but thats normal, those that can do and those that can not complain.
The 51K is just a asking price, like anything else. Most here had a 36-40K asking price and ended up paying lower 30K's at the end of the deal. I never liked customized vans or trucks from places like Choo Choo Customs, but they make them and people buy them. They are also the same people that can not do things for themselves, but want the look of a custom truck. It's funny because a custom truck is defined as a one of a kind, unique to itself. There is nothing custom about a truck that is mass produced and they all look alike.
Someone will buy the truck and be happy with it.
