I saw your add on Myswag, and like many here though it looked good, but not a flash ad (sorry - not trying to be mean).
Have you read through this thread that McGirr wrote up?
Topic: Tips on selling campersAs JCOJ mentioned it's the 3P's - Promotion, Presentation, Price.
Marks thread lists the important points - Pictures, Pictures, Pictures.
But not just trawling through the holidays snaps to get a few.
Take it out to a nice location, and take loads of pictures at every stage, from various angles so you can choose.
Same as selling a house - take your stuff out of it, and make it into a story that the viewer can picture themselves doing, and experiencing.
Regardless of the forum you put it on - the quality of the pictures and narrative / story to hook a buyer remains the same.
Me - I'd rather buy a camper trailer, but the missus wants a house, maybe I can park a camper trailer outside the house.....
Good luck with the sale.
