Throwing this out there to see if anyone has a need. Price is right,
if you do.
Posted to W&W and local craigslist. CL has a couple pics:

Body of add, should that be preferred:
Enclosed glider trailer.
Homebuilt. Tows well with 1 7/8” ball. Aluminum skin over aluminum
tube frames construction. Recent trailer tires with very low miles.
That was ~$235 itself.

~27 feet long, 43" tall plus rudder box. 60" wide. Cavernous, really.
Very generous trailer-front access. Fuse dolly and wing dollies
included. Nose cone/catch is not included.

NOTE: Because of construction style, this could be modified without
that much trouble, to be used for anything else that needs an enclosed
trailer and will fit inside.

Not super pretty, but the price is right if you need to get a glider
or something else out of the elements. $500.
Located in Everett, Wa.
