Selling our beloved RPod

We have a 2014 176t RPod that we would like to sell.  I am posting this on the owners’ forum because I’m looking for advice.  We’ve not sold or bought a trailer online and would like advice about the best site/way to do it.

The RPod has been modified using many ideas from this forum. The bench between the table and bed now sits up to make a nice sitting area, the heavy table replaced with a lightweight folding one, windows all covered with cellular shades, storage under the dining bench opened up with roll-out shelves, space under the sink opened up to hold our coffee makings, a wine glass holder over the sink and knife magnetic strip on the kitchen wall, wine bottle holders on the entertainment unit, access to storage under the bottom bunk modified to be through a sliding panel on the front, and a memory foam queen mattress on the large bed.  All lights, inside and out, are now LED. Outside, a double propane tank holder and spare tire holder were added to the hitch in front to make dry camping easier. We used the RDome as a canopy, but not the front panel, which was hard to use if the land was not perfectly level (which no campsite we’ve used has ever been). 

Ideas?
