Most Popular 3001 - 4000 lbs for Forest River Rockwood Windjammer Travel Trailer

My Jack arrived DOA. After installing it on my trailer, the Jack didn’t work. The manual crank handle came in handy because I didn’t have time to troubleshoot and repair it at the time. It was just a wire that was no longer connected to the switch but I have to tell you it was extremely disappointing to receive a brand new item that didn’t work. If it had worked out of the box, I’d give it a five star review. You should consider soldering and heat shrinking the wires to the switches or making the wires longer so they aren’t banjo string tight and putting the lug at a strange angle.

Great product and Trailer has great customer service. It's to bad that the shipping companies do not take better care with the items during shipping! will receive replacement parts to fix what was broken, but it causes lots of extra work for the customer. will have to take complete jack off to replace the broken motor cover because of shipping carelessness!! regards, Dan Ewert

This is what I needed. I Wanted a little more lbs. of lift so I could lift my truck for weight bars and such. I have a 2014 Rockwood A Fram and needed the mounting holes to line up. After some research, I found Stromberg jet-3755 worked perfectly. I have used it for a year now and no problems. Easy to set up and use. Thank you etrailer

Item arrived a day early. Installation was easy. Jack works smoothly. 3500# rating is 500# better than the factory installed jack.

The product works as designed. Easy to install and I have used it approximately 20 times in the last year. The storage for the 7 pin connector and safety chains are a great option. Keeps things nice and tidy when unhooked. I highly recommend this Jack.

Perfect fit and operates very quietly and with abundant power for my 27 foot Lance travel trailer. The Jack-It Lippert bike rack mount fits perfectly over it, and the manual emergency jack crank fits within the tube of the Jack-it if the need arises. Also, the handy ring for stowing the trailer chains and receptacle for stowing the 7-way connector is a nice feature. Very happy with my purchase, and etrailer is fantastic, as usual!

I love the feature of the auto retract, however, it is super slow. Either way, I can now confidently walk away from my ice shack and know the jack will fully retract every time.

I purchased this jack because it is the exact same model as the jack installed on the trailer at the factory. I have attached a photo of the one I removed. I had the trailer power washed and the spray damaged the membrane that covered the three switches that operate the jack. The resulting exposure damaged the switches which could not be repaired. Not the best design in my opinion.

I should have got one years ago. I only use it when it's connected to the truck with the engine running. This I believe gives me full power. It has enough power to raise the trailer when connected to the truck to get the anti sway bars attached. Sure beats all that hand cranking.

The alternate power setup makes its slow rate of rise necessary which would be good if my lithium batteries went low. To avoid battery problems be sure to add an inline battery disconnect from the trailer power when using tow vehicle power. I simple added an inline fuse that could be removed should I need to use the tow vehicle power.
