That happens a lot on this forum. People claim that they are going to take the truck to all sorts of neat places etc etc, and then lots of subscribe to the thread. And then when done they sell it for a juicy price.Such a nice build. Crazy that someone would have something like that built then suddenly decide they don't need it anymore. `
It seems to be a way of running a long term high visibility advertisement without paying for it. This is definitely not the only case of this on this forum.
Although to be fair not sure if the guy who posted the ad on this forum was a proxy for the builder or actually bought it from the builder and changed his mind.
