We needed to rotate a 21 foot travel trailer in a tight space. This product was easily installed and ran off of the battery in the trailer. That was a bonus. Our driveway has a slight slope to it, the traction wheel had difficulty going up-grade over the transition between slabs. A little push solved that. The trailer was moved in about 10 minutes. This is not fast but it did 100% of what it's supposed to do. The only reason that it's not 5 stars is the mounting bracket flexes a hella lot. I mounted it correctly before you're all like "this guy doesn't know crap about" Nah, mounted correctly. Did layout work, drilled and deburred the holes, dry fit and then torqued everything. It's still sketchy....but it did it without failing. So, mission success! Thank you!
