Tell us a little more about your needs - where the trailer needs to go, grade, surface, obstacles etc. I've found all of these come in to play, and some solutions work much better than others given your particular environment.
I've become somewhat adept at moving trailers around my property...I've got 5 of them, including two with boats atop. They all go in/out of tight places routinely. My tools of the trade:
- Front mounted hitch. Much more maneuverable than a rear mount hitch, but not always the best when trying to squeeze something into a garage corner.
- Ball hitch on back of tractor's 3-point. It's very fast to hook up (can do it from the seat), as maneuverable as the front mount hitch on the truck, and gives me the ability to place trailers where I can't/won't drive my truck. Certainly not an option for everyone, but for those who have one - just do it. You'll never use your vehicle's front or rear hitch around the house again.
- Electric trailer dolly. By far the most maneuverable, but it's slow and is limited to flat/smooth ground. It will usually work across level and groomed gravel, but not always - any small obstacle a trailer tire encounters can hang it up. It's ideal for asphalt/concrete - nothing better. Also, I wouldn't go with one that has a ball mount. Those with their own adaptors (Powercaster and Powermover) are much easier to attach, more stable, and maneuver more easily given that they mount back of the ball.
- Manual trailer dolly. I actually use this one a lot on concrete for smaller trailers. Works nicely with my 16 and 5x8 trailer, but too small for anything bigger/heavier.
