I have a set of 8 inch wheels that allow me to get the trailer into the garage with about an inch to spare under the door frame.
With the vent closed, that is, #$%^.
If you put wheel jacks on not only the tongue but also the bumper corners you could wheel it around freely with to tires on. I did this not only for leveling but so I could maneuver it in the garage when I needed to get at something it is blocking.
