I have a 6 x 10 Haulmark Trailer in new condition. Includes custom painted murals on both sides w/side door and roof vent, spare tire, sliding shelf that allows you to store all your astronomy equipment that slides forward to allow carrying a 24" rocker box in the back end. Then when the scope is in use the shelf can be moved towards the back to allow easy access to your equipment including a star chart shelf.....red lights and all under a canopy to help fight off the dew.
Trailer also has a loading ramp that lets you wheel barrel your scope in or out. When not being used, it is your bed platform in the front of the trailer. Have pic's availiable.
Would consider trades.
