+1 on the Trailer Valet. Works very well on single axle trailers, a bit tougher on dual axles but still doable. On smooth level surfaces, like the floor of my very large shop, I also find it pretty convenient to just set the front jack stand pad on a metal four wheeler (I.e., Harbor Freightís auto wheel dolly) and then just push the trailer around. This works for both single and dual axle trailers. For very heavy trailers, I use a Power Caster good for up to 18k pounds. Couldnít live without it.
