If an add doesn't have pics I don't even look. You need to add some pics. of the tires and of the inside. Several pics of the inside.
List what weight the axles are (GVWR is also ok)
Tire condition.
Deminsions of outside / inside and also rear door.
Any accessories you have in it.
As grumpy as some people are (and to lazy to respond to mssgs) if a buyer has many questions they want even bother asking.
When I was looking for a trailer I needed to know all the answers above. I sent several people questions and even listed them 1-5. You'd be supprised how many people would only answer some of the questions.
Needless to say I didn't buy from them.
Remember you can NOT have too much info listed about what you are selling. The more detail ( specs) you have the more professional your add is.
Your trailer is listed at a good price, but it is above what most guys want to pay for a trailer. I would like a 40' just like yours and I need the hitch adapter you have in the pic. (you didn't mention that in your add and you should), but can't pay that much for just a trailer. There are several (older, but) with living quarters for the same amount (or less)listed on RJ.
That would serve my needs better. You also have to remember people will pay way more from a dealer than they will from an individual.
It looks like a nice trailer and somebody looking for a new(er) trailer will buy it. Income tax is starting to come in so maybe that will help.
