Folding campers seem to sell well on eBay. The auctions that seem to get the most attention -- and thus higher bids -- are also the most thorough.

Three main things to include: specifications about the trailer, its current condition, and PLENTY of photographs.

First, Pricing.

There are websites that have appraisals of most trailers over the past decade. For instance, Nada Guides has pretty good information. This gives you an idea of what your trailer might sell for. I've looked at LOTS of trailer auctions, and it's amazing how many of them actually sell for the appraised value in the online Nada Guide. (I can't link to non-ebay sites on this guide -- just do a google search for Noda Guide!).

Specifications

Unlike cars, it's difficult to find specifics online about used trailers. If you're selling a car, there are several websites with photos, specifications, reviews and a lot more about most cars over the years. Unfortunately, this doesn't exist for RV's (not that I can find).

Include every specification you can. Including:

• Model Info. Include the manufacturer (i.e. Fleetwood), model, and actual model #. This information should be on the sticker on the exterior of your trailer, or on your owner's manuals.
  
• Dimensions (width, length and height) when the camper is open and closed. The closed dimensions are important if a potential bidder is trying to determine if it will fit in their garage or other storage area.
• Sleeping capacity. Include the number of people the trailer is rated to sleep, plus the number of beds. For instance, if you have a front and rear bed, and a dinette plus a sofa that convert to beds, mention that there are 4 sleeping areas, and where they are. Give the dimensions of the beds and what size sheet they use (king, queen, double, or twin).
• Features. List every feature. Including things like:
• Refrigerator
• Stove(s)
• all lights
• storage spaces
• water tank capacity
• water heater size and BTU's
• Air conditioning (with BTU's)
• Slide-outs
• awning, with dimensions
  
• Add-a-room (screen room) with dimension
• Brakes (electric or hydraulic, or none)
• Spare tire
• Tire and propane tank covers
• Whether owner's manuals are included
  
• Towing Information. Ball size required. All weight ratings (GWVR, GAWR, tongue weight).
  

Condition

It is extremely important to be thorough and honest about the condition of the camper. You don't want to be in a situation where someone has won your trailer and the condition is worse than you described.

Remember, potential bidders are looking at USED trailers, so they should expect it to have some wear and tear. Unless you never used your trailer, it will have some wear and tear. Be sure to mention it up front to prevent any problems later. Otherwise, the buyer will assume it's in PERFECT (like new) condition, and can retract their bid when they learn it's not.

Some important things to include:

• How often the trailer was used when you owned it (and previous owners, if you know)
• Amount of rust
• Any tears in the canvas or screens
• Any mildew or mold
• Cleanliness of the trailer (interior and exterior)
• Whether any features don't work 100% properly
• Any damage to the roof
• Missing or damaged gaskets or other features
• Condition of the tires, battery, etc.
  
• What type of vehicle(s) you've towed it with (and how well that vehicle towed!)

If you have an idea of how much any repairs might cost, it's good to include that information. For instance, if your trailer has a cracked skylight/vent, that might be a $20 part plus labor.

Be sure to mention any recent repairs or replacements. If that A/C is brand new, that might increase the value of the trailer!

Photos

We live in the age of digital photos, which means you can take LOTS of photos without costing any money. Include lots of photos of your trailer.

Some important angles:

• If you have a floorplan of the exact model (maybe in a brochure, from the manufacturer's website, or elsewhere on the web), that is EXTREMELY USEFUL.
• Trailer exterior, folded up. Shoot it from the front and back, so the buyer can see all 4 sides between the two photos.
• Trailer set up - exterior, from the front and back
• Trailer interior:
• A close-up of the kitchen/galley
• Get on each end bed and shoot a photo of the entire trailer from that perspective. This is extremely important, so the buyer can get an idea of the floorplan.
• Photos of the sleeping areas. Convert the dinette and sofas to beds, so the person can get an idea of the size.
• Photos of the air conditioner and any other important features
• Photos of ANY damage, like mold, mildew, broken cabinets, tables missing the edge or laminated top, and photos of the flooring if it has damage
• Close-up of the flooring and the drapes
  
• EVERY FLAW should be photographed, close-up, so the buyer understands the flaw. If there is a lot of rust on the frame, for instance, shoot a few photos of the rust and explain where that rust is located.
• Photo inside the front storage area, if equipped.

Some photo tips:

• Bright photos. I see tons of eBay auctions with dark photos. How do you avoid dark photos? LIGHT! If you take a photo and it turns out dark, set up a work light or other bright light to help illuminate the trailer (NOT just the trailer's own lights). Use the flash if you're shooting close-ups of the galley or damage.
  
• No blurry photos. Most digital cameras (in my opinion) shoot blurry photos. One way to avoid blurry photos is to A) use a tripod or B) use the flash. Try one of those to avoid blurry photos.
• No tiny photos. Your customers are looking at photos to learn about the trailer. Don't put tiny photos on your auction. The larger the photos, the better your customer can understand the features.

Unfortunately, this eBay guide section is shrinking my photos. Regardless, this was shot from the bed. This shot helps bidders understand the floorplan. Be sure to include this shot, and the same shot but from the opposite bed.
