mrccplus - welcome to the forum!
I'm going to point out that I think you've misstated the towing height. I think if you check, you'll find the roof of the trailer is about 6' high when the top is lowered. And, if you plan to store it under cover, you have to add about 8" for the Air Conditioner, which sits on top of the roof.
It will help your sale if you include pictures, inside and out.
