Purchased a Powercaster PC-3 power dolly to turn around my Nitro 31FQSL in a really tight driveway. I was able to get a very good deal on Craigslist. The design of the powercaster is old school but very robust. The unit attaches to the electric trailer brakes. It has a momentary stop and parking brake. Unit is powered by a 120volt source.
My unit is over 10,000lb dry weight and over 1200lb tongue weight. The powercaster had no problem running the rig up a slope and on to Anderson levelers. Turning requires a bit of tugging but isn't too bad. Utilizing the trailer brakes makes the move a comfortable and safe move for one person.
Very pleased with the purchase and would highly recommend this brand if you are in the market for such an item.
