Due to limited yard space I have had to fight using a manual trailer dolly with my standie. It was not a problem with my teardrop but the much harder Kenskill standie got so hard I almost skipped a rally or two just to avoid the work of hand moving it. I finally found a solution, the Trailer Valet
https://www.trailervalet.com/. It works better for a shorter person but it is still a life saver.
I have the model that is attached to the side for the tongue which works well but due to the tongue/electric box/battery being in a short space i had to remove the propane tanks. That is an annoyance but I can get along without it or bring a separate tank if I need it.
There is a new more expensive model that uses a trailer ball attachment. I have not see that one in action but one I have is a life saver. I highly recommend it to anyone needing to more a trailer in limited spaces. I got mine through
