Best when planning to sell a coach is to think of it in the same light as selling a home. Clean EVERYTHING. You want the coach to sparkle inside and out. De-personalize the interior a bit but don't empty it. Staging will get attention. Place settings at the dining table (think semi formal dining not paper plates, red solo cups and plastic flatwear). A few stables in the fridge/freezer and kitchen cabinets. You can even use empty packages to give a buyer an idea of size and space available. Towels on every towel rack and a fresh roll of TP but remove personal care items (soaps, shampoo, hair brushes and such). Bed and pillow coverings in place, maybe a few throw pillows or a small blanket on the couch but not something covering it as if you're hiding wear or stains. All lights on, interior and exterior. TV on and rear view camera operating. A pic of the dash with the engine running and no RED WARNING lights (not even the parking brake on light but showing engine RPM, water temp, air pressure and sush at normal limits). Consider a walk around video. Take pics (interior and exterior) of the coach ready for travel with the slides in and as it would be at a camp site with the slides out and awnings deployed. And don't forget what might be in the back ground when taking exterior shots or what can be seen thru the windows. Your neighbors laundry of under garments out to dry on the line might be better if not seen.
May of the selling sites will not allow unlimited pics or a video but there are plenty of sites that will hold the images as an album and allow you to include a link to the collection, for free. You can link a You Tube video also. Preview, preview and preview what you are up loading. Blurry, overly dark or bright, rotated incorrectly and other such errors you want to avoid. Retake the pic if necessary. If you can include a description of what the pic is then do so. For national listings
RV Trader and
RVT are the first to come to mind. eBay gets national coverage also but buyers can be a bit hesitant to bid without seeing first. Craig's List is a good local source and their search engine will provide regional results. Just do a web search with the term "Used RV Listings" to give you an idea of the various sites.
Reformat your images from the very high resolution original down to something between 800 x 600 to 1280 x 800. The low resolution allows for faster down load and full viewing on something like a cell phone, tablet or laptop PC without having to scroll around or resize the image to suit the viewers screen. Too small is also bad so stay above 640 x 480 resolution. If you can get your hands on a GoPro camera it takes very good wide angle stills and video. The GoPro will need good lighting to give you maximum performamce.
It's a lot of effort to stage, photograph and write an advertising description but worth the time to do it right. It’s a bit of a subliminal message to a buyer. A well documented listing gets remembered and a well staged coach shows pride of ownership. Or you can just list it in the local Penny Saver as is where is for what ever seems like a good price and be done.
Edit:
HERE is an example I just came across of how not to list. One slightly out of focus cell phone pic rotated incorrectly 90 degrees with tree covering part of the coach and more ground then rig. Also a one line discription. To bad the seller didn't take the time to do a better listing. It's the make, model and year range I want that is only just outside my price limit. I like the rig but with a few clicks of the mouse I can find a much better listing without have to make a call or send an email requesting basic info.
