I dont know anything about your rig or even where you are but no bites or nibbles usually means it isn't priced to sell or the ad is just not interesting.
Even at the very fair price of 73,000 (Just under NADA value) it would be tough in this market. Dealers are selling rigs that have 120,000 price tags for 75,000, brand new with warantee. Some friends of mine just bought a LOADED 2011 34' class A bunkhouse with 2 slides, the MSRP was 122,000 they paid 75K tax and license included. I wouldn't want to be competing with that as a private party. Your Bounder is a better rig than the Coachman, but brand new for the same price is still brand new.
Since I dont know the price of your rig I can only guess from the NADA value. In today's market people just aren't paying over low NADA for much of anything, and most lenders are so burned on RVs they wont even loan more than 75% of low NADA on a used rig. That was what I heard from 2 different banks I talked to. USAA being an amazing exception to that rule.
I recently bought a rig (Bounder as a matter of fact) priced well below book that had no interest what so ever. I was the first caller who actually showed up to look at it. It was listed in RVTraderonline, craigslist, and RVT. The pictures were nice the ad was no nonsense and the specs on the rig were outstanding and the price was thousands below low book! Why was I the first in over a month to respond? The ad had no flair, nothing of interest. For lack of a better description it was poorly marketed.
When I sold my 1993 Pinnacle it was on the market for around 3 months and I only posted it on Craigslist. I followed the rules and didn't re-post in under 3 days but I always made sure it was posted Friday morning. So I would post Friday and Tuesday mornings. If I didn't get at least 1 call per posting something was wrong, price was too high or description must be turning people off. So for the first month I tweaked the price a LOT and rewrote the ad several times. We initially wanted 12k for the rig and took 10,500 but the ad read like an interesting story in which Penny the Pinnacle was the pampered star of the show! Everyone who responded said they loved the ad and wanted to meet Penny in person. I mentioned that I sold her for 10,500 high NADA value on Penny was $6800. A well written ad and a good price are the only ways I found to get a rig sold private party these days.
Good luck, and I hope this was helpful.
