I sold my older mobile home on Craigslist in Phoenix this past summer. It was an interesting experience. Just know that it is basically impossible to get a loan to buy a mobile home now, so your price may need to be low enough that someone will have access to the cash. I was 1 for 2, I couldn't sell my Mom's mobile in the same park, she had to sign it over to the park. It was nicer than mine, and she wanted less. The fates can be fickle. I was more patient than she was. It took about 3 months, and the first few iterations of the ad didn't get me much. Once folks started looking, I had a steady stream (ok, a couple a week) looking. I reduced the price a couple of times.
Not sure what your market is where you are. Mine was the +55 snowbird area. The prospective buyers also had to pass the requirements to live in the park, which included a background check and net worth minimum (which was new with this new manager). The manager scared off at least one buyer with her attitude.
Just things to think about. I ended up getting the reduced price I wanted, because these buyers scoped out the manager and told her that they wanted one of the mobiles she had for sale. At the last minute after they were approved to live in the park they 'changed their mind' and bought mine. Hopefully you do not have the Wicked Witch of the West as a park manager
