Allan Tone was the owner of the company formerly known as SprinterEngineering out of Salt Lake City. I ordered a pair of swivel seats from him and after 3 months of run-around I got an email saying he has gone out business. I’ve been able to reach out to other people who have done business with him and this seems to be his mode of operation. Start a business take a bunch of peoples money then move on to the next thing. On one website he describes himself as a “serial entrepreneur”. I would not be surprised if he pops up again doing van conversion and selling parts. Save yourself the hassle and if you see the name Allan Tone RUN!!!
