I have an aluminum tube framed dolly for my 2000 pound Northern Lite which is very useful in moving it around without having to load it. However, it isn't the easiest thing to move on your own. If you are on a polished concrete floor I would say no problem. But, if you're outside on concrete (mine is a broom finished concrete) with ANY debris, sand, really anything, that gets in the way of the castors it will be difficult. Its amazing how small of a pebble will stop it in its tracks. Plus, if the concrete is sloped that is another issue.
I mounted a tow-bar on the front to help move it most of the way when I'm just going straight out and back.
I use mine primarily to shuffle spots between by fifth wheel and camper. My storage area is deep buy only one lane wide.
