Quick Products JQ-3500W Power A-Frame Electric Tongue Jack with LED Work Light and Permanent Ground Wiring for Camper Trailer, RV - 3,650 lbs. Capacity (Higher then Standard 3,500 lbs. Jack!), White

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.

Held up perfectly over 5 years and still going strong. Not a single issue. This worked quicker and better than the jack on my new camper, raises and lowers twice as quickly. Easy to install and the bubble level was very accurage. Very happy with this.

Well please don't judge me but this is my second one entirely self afflicted. I would buy this again and again. Entirely dependable and affordable. Fantastic product!

The unit arrived from Amazon on time and was well packaged. Installation was simple and went smoothly. Switches and lights work as expected. So far 5 stars for the hardware. I will update later regarding performance and reliability. The reasons for 4 stars vs. 5 were the instructions and the bull's-eye level.Wiring Connections: The wiring instructions are inadequate for anyone not familiar with electrical circuitry. 1) Installation step 9 says to route the black wire "towards the battery" but never says to connect it to anything. Worse yet the next sentence says to "Attach the [same] wire lead to the trailer using cable ties." This could lead someone to attach the wire to the frame as would be done with a ground wire. Farfetched? Perhaps, but Murphy's law prevails. 2) Step 11 says to connect the lead from the fuse holder to the battery's "+" terminal, but which lead? There are two leads one stamped "line" and the other stamped "load." What it should state is, "Connect the `line' lead to the `+' terminal of the battery and connect the `load' lead to the black wire leading from the motor."Manual Crank: The instructions never describe use of the manual crank. It looks like there is a cap of some sort under the bubble level but does it lift off, unscrew, or do the three small screws around the level have to be removed? I am reluctant to experiment not knowing what will happen when I start removing screws or twist the cap and break something. Advice anyone? In my case I cannot use the crank provided with the jack because it interferes with the propane tanks, but I could probably use my electric drill with a socket.....if I could access the drive point.Bull's-Eye Level: determining what is level in a camp trailer is subjective. Place a level anywhere in the unit and you will get a different indication. I use the grate over the stove burners as my level reference. Everything else can be a few degrees off and be unnoticeable. Once that is level I mount a bull's-eye level with epoxy somewhere on the hitch so that the bubble is centered. However, after mounting the Jack Quick 3500 the integrated level was too far off center to be useful (a half bubble right and up). Not surprisingly my hitch is not in a parallel plane with the stove. It would be far better if the level was included as a separate item so the end user could establish her own level reference and epoxy it appropriately.Recommendation: A good product at a fair price.2014/04/09 update.Manual Crank: The manual crank is accessed by turning the knurled knob beneath the bull's-eye level one quarter turn ccw. This simple one-liner should have been included in the instructions. My 3/8" electric drill does not have enough torque to turn the 11mm nut. Fortunately, by removing the shroud from the propane tanks I have enough clearance to use the crank should manual operation be necessary.Bull's-Eye Level: I suggest the following:1) Remove the three Phillip's head screws surrounding the level and discard them2) Remove the level3) Level the unit using your chosen reference (stove, refrigerator, table, etc.)4) Apply epoxy to the base of the level and replace it, supporting it with the bubble centered until the epoxy dries.2014/06/22 Update. We just completed a 4-week 5,000-mile trip. The jack performed flawlessly.
