3500W Heavy Duty A-Frame Electric Tongue Jack with LED Work Light - 3650 lbs Capacity for Camper Trailer & RV - Permanent Ground Wiring, White - Perfect for Easy RV Leveling, Hitching, and Stable Parking on Uneven Terrain

After reading several reviews about this jack, both bad and good, I hesitantly ordered it due mainly to the low price and Amazons Return policy (best by far, if you ask me). The good reviews outweighed the bad and the most receent ones were all 4's and 5's. This often means that a company finally stepped up and fixed what was wrong and has the problem corrected. This must be the case when it comes to this jack. Mine arrived packaged in styrofoam in a cardboard box with no obvious signs of damage. Becvause of the revviews of ground wires not being connected, I decided to bench test this before I attempted installing it on my recently aquired camper. Using a set of jumper cables, hooking one end (black) to the bare foot metal and the other (red wire) to power wire. Both the light and the jack motor operated just fine when the switches were pressed. On to installation. I already had the old jack off in antcipation of the arrival of this one. I've used the manual/crank jack for 18 years. It's still working fine, but in my 50's, me not so much. Plus I use to have sons living at home to do all the hard stuff. Mounted the jack in about 10 minutes. The leveling, center bubble on top of the jack was off a bit, so I double checked the camper for level both directions and then loosened the three bolts and repositioned the jack as close as I could the bubble to center. It depends on how and which bolts you tighted up first, as to where the bubble wound up. This is for a 35 foot, bumper hitch camper so leveling is big deal as far as how everything opens/closes and drains. Happy with the placement the second time around. Nest run the single wire back to the positive terminal on the battery and wire in the included 30 amp breaker. Not included is one large wire nut or a crimp type wire splice to tie the two together and a large eyelet terminal to connect to the battery. Being both a mechanic and professional handyman, I happned to have both laying around in the garage, so no trip to the hardware or auto parts store. The jack has an internal ground and comes with three star washers so that when you tighten up the bolts you make a good ground. Installation complete and time to test the jacks speed and power. Hit the switch and the jack jumps into action. Under no load moves very quick. The weight of the camper slows it down a bit, but in no way, shape or form does it seem to strain. My camper is a 2006, 35 foot Montana with two slides and by no means a light load. This one moved it up and down effortlessly. Several reviews talk about it being slow. Either they've never used on of these before or they don't understand the laws of phyics using gear reduction so that a smaller motor of cylinder can do a much greater amount of work than would seem physically possible for something, no bigger than it is. As for the noise, I use to make more noise than this jack does when I had to crank it up and down several times by hand, through the set up process.
