How heavy is it? This might be ghetto but if its light enough why not put it in the garage, above your cars, eathier in the rafters or make a pull or tow straps and just have it be raised above your cars and suspended up there.
Always thought about doing this with my jetski trailer or my old 4x6 utility trailer that was light as heck.
Or stand it on its end or its side and put it up against a wall.
Edit is it a open trailer or enclosed?
