Here are a couple of ways that have worked for me. In So Ca we have a book called the RV Trader. I first listed my 1990 Flair 26 there. Next, I found a side street right by a busy intersection where I parked the MH early in the morning. Traffic backs up for a long way and people are bored and my big for sale sign caught their attention. I made up a flyer and put them in one of those plastic boxes you see in front of houses for sale. I hung the box on the windshield.
Additionally, and everyone laughs at this, but I took the MH to a massive shopping center on a week end and parked in the Walmart parking lot and held an open house. I got a couple of offers from the "side street" location, but eventually sold it to a couple that came to my open house at Walmart.
I sold it in 3 weeks but it was a lot of work and those 3 weeks seemed like 6 months. Be prepared for every tire kicker in the world plus people who have no money and want you to finance it for them. Then there are those that pick the unit apart - I mean it is a 1990. If you want perfection, look at new ones. Then there are those that have no place to keep the unit. Then there are those that just like to look at MH's. I meet a lot of nice people but I also ran into some loons!!
