Motorized Trailer Dolly ??

Looking for input on a motorized trailer dolly. Anyone ever used one? I’m considering something like the Trax. I need one with enough power to move a 21’ Triton tandem axel in a tight space. Will be going up a slight grade so the hand dolly from Harbor Freight just won’t work. Looking for options. Thanks in advance.

Loved my Trailer Valet XL when I needed it. Moved recently and now have a shop.

I use the Parkit 360. Works great.

Thanks for info guys. Will def check these out.
