Best 6x12 enclosed trailer

Would like to get one of these to haul supplies occasionally. I can probably make due with a 6x10 or a 6x14, but the whole thing needs to be less than 96” tall (8’). The height restriction might be a bit challenging as some trailers this size are over 8’ tall.

Do you guys have any of these in south Louisiana? If so, what brands or setups do you prefer?
