I received my AC6 Powermover yesterday. It is stout - generally over-built. It is a well thought-out design - much of it appears to be fabricated by hand. It is VERY easy to use. It requires a little bit of muscle to mechanically connect to the tongue-mounted bracket, but not too much. I suspect it will get easier with practice. Electrical connections include the trailer's 7-way cord, 120 VAC from a wall-outlet (80' cord included), and two clamp leads to connect to your tongue mounted trailer battery (to power the trailer's brakes). During operation I found that I was fighting with it like I always do with my snowblower. When I relaxed the mover did all the work. It is very easy to turn. It moves at just the right speed too. The unit arrived well packaged with no signs of wear. The four bolts that clamp the docking connector onto the tongue of the trailer were too long, so I had to go to the hardware store to get shorter ones. I plan to change out the forward-off-reverse toggle switch with a locking-lever style to make it more difficult to accidentally change the motor direction while in motion (this is apparently very bad for the motor). I was easily able to move my trailer in and out of my garage several times with just a few inches to spare on each side. I kept forgetting to turn off the brakes on the trailer. When I would try to move it the Powermover's wheels would just spin. Each time I would eventually come to my senses and remember to turn off the brakes. Everything works much more smoothly when the brakes are off.
The Powermover has met my high expectations so far. I recommend this product to anyone who needs assistance moving their trailer around in tight quarters.
DISCLAIMER: I didn't receive any discount for my endorsement, but I do hope to get four replacement bolts out of the deal.
