Installed on a 2018 E350 Ford Minnie Winnie. The package arrived really beat up but only a single cover was damaged. It was replaced quickly. Nothing was missing. I had to shim it down from the frame about 1.5 inches using a bar of 1.5"x3"x 24" inch aluminum stock on each side. Then it would clear the fuel tank and the gray water. Switches are installed in our garage under the bed. Wiring came from power panel which is fairly close to the switches so it all went fairly well. Wire nuts are not recommended so I had to hunt around to find connectors that would work. I have not used it for camping so do not how well it will work to stabilize the vehicle. We do a lot of boon docking so will have to have some good blocking to level and stabilize. It feels a little better sitting on the street. I do wish there was a lockout for them being raised before moving the vehicle outside of PARK?

Very pleased. Not that hard to install. These replace the weak stabilizers that came with the trailer. You'll need a jack and an electrical kit to complete the install.

Still working just fine, Ive suggested it to anyone who askes about it.

Your going to love this product. I was able to fit on to a 1987 Avion travel trailer I renovated for my sister (spectacular renovation). It made the camper rock solid. You can't feel anybody walking around, no high wind movement. It felt like we set it on a concrete foundation. It is a well designed product I will use in the future if I renovate another classic beauty, even my own every day travel trailer. Great product.

Excellent product

I got the jack for three reasons. My original jack was intermittent, it was bent and it did not level the trailer because it had only one motor. The new jack works great and it can level the trailer because it has two motors and the power required. It was not the easiest to install because of the increased size and it will not level the trailer if it is off more that 2 inches or so side to side. In spite of these drawbacks and the fact it added weight to the rear of the trailer I am very happy with the new jack.


Comments
Good. Only issue I have is it is slower than my old jack

On my 5 whl the landing gears froze up and would not turn either way. I ordered LC179013 and installed myself. That was s good job for an old 70Yrs fat man to do.. I got them installed and wired up and they work like a champ. That has been over a year ago and have been used alot.

Scary at first, but following directions, it bolted right onto the frame, used a floor jack to hold it in place while attaching. Wiring was uncomplicated, except for figuring out where to route the wires. works fine, I am a happy camper!

still works great.

i find these easy to operate. installation took a little time as i had to works underneath the camper. i have discovered, the middle of the jacks flex when leveling. i have some heavy angle iron, i am going to reinforce them. before i do that operation, i am going to add more bolts, that may be the simple solution. overall, excellent product.

Installation was easy, need a helper just to make it safer. CSR people are great very helpful!! Works as promoted and I have recommended this product to other campers.


Comments
Well after 1 year of use the Jacks are still doing very well we have gone on at least a dozen trips that they have been utilized. I am very glad to have purchase them, the installation was very easy great videos!! Best Regards P.S I have recommended to other campers and have even assisted on installing them.

The product itself is a good product but the packaging for shipment is very bad. I received mine and the box was badly torn apart and tapped back together. I was missing multiple pieces and had to wait until the replacement pieces arrived. Customer service was very helpful with resolving this problem within minutes.

I purchased 4 sets of these for 2 trailers. One motor intermittently will not run unless I remove the cover and turn it by hand. It occurred immediately after installation. Should have returned it.

Exact replacement of what was on the Carrilite 5'er with both products, the levelers and the front landing gear. Fast efficient service as usual!

Review from a similar Power Twin II in Camper Jacks


Finally got around to installing my PT II Stabilizers 30" front and rear of our 26' Surveyor. Pre - assembled them to make sure they went together ok. Luckily I had two sources for power front & rear which made wiring easy, I used a Buss block to make all positive connections, grounds straight to frame, soldered all connections and heat srinked to seal. Using the 3/8" self tappers was fun.Well got it all together and all works well makes trailer very stable, don't have to worry about scissor jacks collapsing anymore.


Comments
Working well they make our trailer very stable compared to the sizzor jacks that came on our trailer well worth the money. Install was easy and had them spot welded to frame.

Review from a similar Power Twin II in Camper Jacks


I received the leveller/stabilizer as expected. The instructions for installation were clear and I found it easy to assemble and install them. Wiring was a bit tricky because of my trailer design, but worked out fine in the end. I have just returned from a three week trip and can recommend this product whole heartedly. One thought I have had is that a manual version might be satisfactory, using a drill to drive the gears until they engage with the ground, and then using a manual crank after that. The motors are a bit slow to drop the feet to the ground because they also have the necessary torque and gear ratios to lift the corner of the trailer. All in all, a great product.


Comments
I continued to use the trailer until parking it for the winter in the fall of 2019. The stabilizers continued to work well. I have nothing further to add, unfortunately, until this pandemic is done.

Review from a similar Power Twin II in Camper Jacks


After installation the stability or my toy hauler was increased X3. The installation was relatively easy and all that was needed was common tools and a floor jack. Wiring was covered by simple easy to follow instruction. Some shrink wrap and a solder gun make permanent water resistant connections which I recommend.

Review from a similar Power Twin II in Camper Jacks


The stabilizer was a great purchase. It has lived up to it’s description as advertised. I did have to make some alterations. Because I have a slide out carrying rack on my 2010 Cougar 5th wheel, I had to weld the stabilizer to the frame so I could use the slide out rack. It works great. I highly recommend the product.


Comments
Great product. The levelers worked as advertised and brought a very noticeable stability to my 5th wheel that was not present with the original equipment that the trailer was equipped with...scissor jacks.

Review from a similar Power Twin II in Camper Jacks


It took a while before I installed it, and it was a pretty involved effort putting it on our 5th wheel but after it was installed it worked as I hoped. Actually my wife wanted it more because she despised it when I used the chordless impact wrench because of the noise it made in a quiet campground. Now it is simple, quiet and I dont use blocks under the jacks so it is a lot quicker to set up and what makes it really nice is my bride can take on that set up/take down task. I didnt give an excellent review because of the effort to install (but truthfully there were no shortcuts to get the equipment installed other than to have paid for someone to do it for me) They also recommended putting the switches in an enclosed box on the rig. That isn't very feasible so I mounted mine on the side of the rig above the jack so you can watch what's happening. I also put exposed weatherproof switch covers on to keep them from getting brushed off or tampered with while traveling. All in all worth the money and effort.

Little intimidating at first, just took my time and it went together without any major problem. The problem that I had was dealt with quickly. It's solid and well built. Print on the instructions was a little small for my eyes. Having the instructions on line was a great help.

Review from a similar Power Twin II in Camper Jacks


Very happy with the quality of this stabilizer jack!! I currently only have the jack installed on one end of our toy hauler and you can feel the difference in how stable the camper is on one end compared to the other end that still has the scissor type jacks. I will definitely be purchasing a second one!!


Comments
I did end up purchasing a second set of these stabilizer jacks a few weeks later and Im very happy I did!!

Review from a similar Power Twin II in Camper Jacks


The Ultra-Fab Power Twin II is a very robust stabilizer and works very well with the two heavy duty twin motor Ultra-Fab landing gear jacks I had previously installed on the front of our 32' fifth wheel. I like this product for it's strength and simplicity. It allows leveling and stabilizing without hand cranking or getting down on knees with a cordless drill and socket. I performed the complete assembly and install myself which replaced the two scissor jacks that came on the fifth wheel. This unit makes for a very stable platform.

Review from a similar Power Twin II in Camper Jacks


The Jacks are considerably more durable well built compared to the Lippert models. The lifting power is real and once on the ground the prevent movement of the RV by orders of magnitude over the other style jacks. I only have one in the center of a long trailer and it has stopped the bouncing and side to side swaying of the trailer. Just stepping onto the stairs to get in its rock solid. Also when all the legs are deployed the doors close way better than they ever had with just the Lippert jacks on the front and back. Definitely recommend to anyone thinking about a better jack than what's provided oem.

Review from a similar Power Twin II in Camper Jacks


I want to give this product 5 stars as they are a very nice set of stabilizer jacks that are very heavy duty but I'd have to say that the quality control from Ultra Fab is not great. The connecting bracket, part # 39-841642 on both sets was very poorly fabricated. On one set the holes were not drilled in a straight line and therefor did not line up with the holes on the jacks forcing me to drill new holes and on the other set the bracket was actually a whole quarter of an inch narrower at one end than the other and the jacks did not even fit into the bracket. Due to time constraints and not being able to be down more than a day after cutting off the old jacks I was forced to cut the bracket and weld it back together straight so that it was usable. Costing me an extra 2 hours of time and frustration. Nice jacks otherwise but I advise to assemble them completely and make sure the parts line up before removing your old parts.

Review from a similar Power Twin II in Camper Jacks


Quick follow up after a year or so of use on the Twill ll Electric Stabilizers. I have one set on rear and one set on front of my 28' Coach. I have found that it is better to use a solid piece of 12"x12" hard wood for the feet to rest on while setting up the camper at site. the plastic ones seem to push in after a bit and I have to re-adjust. As far as the Jacks are concerned, they perform as they should, making the coach very solid with little to no movement. I have had 0 issue's with them since I installed. Not a super easy task by yourself in your driveway but not that hard either. just take your time, run heavy gauge wire for power so no drop in amp. all good! thanks,
