We spent around 3 months looking for our Jayco last year.
Checked the following
Trading Post
Caravan and Camping Sales
Ebay
Gumtree
Plus various forum classified
Ended up finding ours on Trading Post.
90% of buyers would check the above sites, so unless listings are free I personally don't see any real benefit in multiple listings.
Campers are one of the hardest things to get a gauge of 'market value', as peoples asking prices seem to dramatically vary.
Makes it hard for a first time buyer as they see the bargins and it sets an expectation.
I ended up ignoring the year make and based is on condition and features/extras. I wouldn't call ours a 'bargin' find, but definitely didn't get ripped.
I found I sort of steered clear of ebay auctions as It was hard to arrange an inspection prior. Seems alot of bidders are happy to bid without inspection and then pull out of the deal when they go to pick up! So many get relisted due to 'non paying buyers'.
It has been a tough time to sell. I just had a classifieds surf last night and there are still a few for sale that were for sale back in September. Page Bro's Jayco still have the same 2nd stock I looked at last September and $500 is the most they would budge on!
IMHO, for the price you have on it, I'd suggest spend the weekend washing and polishing the **** out of it all, and taking some new photos with good lighting inside, out under and over.
Nice and shiny with nice tight canvas like in a showroom will always look better
Theres another trailer on here for $50,000 + with 3 photos of the outside and a distant shot if it setup camping on a beach.. Doesn't look appealing to me.
This X 1000!
Nothing worse than lazy sellers only using their holiday photos (usally taken from 2km away) with all their crap lying around, or a token pic taken of it packed up in the garage with crap all around it. 90% of the time I closed the ad and looked elsewhere as I figured the owner would have no interest in setting it up for viewing. Also be prepared to set it up for any potential buyers, it's only an hour out of your life at the most!
Heck I just sold 2 old tents on ebay for stupid prices. I set both of them up properly in a decent setting and took a ton of photos. One of them had broken zippers and there was still a bidding war for it!
