The control panel is working perfectly. I very much appreciated the help I got from etrailer staff that helped me find the correct conversion controller which saved me from having to buy a whole new step for my RV. Always great service.
Simple swap!
Almost a plug and play item except for having to connect the new plug end via wire connectors.
You do have to switch the wires on the magnetic door sensor too.
Works better than the original!
I haven’t got it installed yet, but the shipping was fast and can’t wait to have it put in!
Just installed the kit this afternoon and everything working. Everywhere I read said you must change the magnetic switches, but when I put power to the step it worked before I had a chance to change the switches, it works in all modes with the old switches.
Good fit for my old 25 years old RV
I have a 40 series step that was getting unreliable.
I replaced the controller and motor \ gearbox with the LC379145 kit.
The old harness plug was changed to the new one.
The only thing I had to supply was a few butt connectors and zip ties.
Everything bolted up and works just like it is supposed to.
Step now works like it is supposed to
Easy to install- exact replacement of factory installed equipment.
This replacement part fit perfectly and easy to install. I recommend it.
I installed this kit on a customers RV and he happy it works great. I have not heard from him for any warranty or complaint. I will use this company when needed.

I havent heard anything from the customer. Good news
Very good customer service, and received my order on time.
The job and the finished result turned out perfect, the steps work like brand new !! Thanks for the help etrailer !!
Everything needed was in the package and I self installed with no problems. I made one minor error on the install but was able to correct the situation after some trial and error. I will say that you need to connect the step linkage before you activate motor to see if it works.
I had a couple of follow up questions on a couple of wires and after contacting trailer Kevin answered my questions satisfactorily and in a very timely manner.
Has worked flawlessly
STILL WORKING!!!!!!!!!

no problems,great product
VERY EASY install, I lengthened the mag door switch leads to clean up the wiring, making future maint. easier. Operational checks as advertised. Wiring diagrams and tech data also VERY helpfull. Quiet, Smooth operation. Had been experiencing intermittent operation and occasional gear box lockup with our unit.
These people are always available by phone and fully knowledgeable. I recommend etrailer anytime. A +++
Fit perfectly. Worked like a charm but make sure you use the new magnetic switch, that was my only stumbling block.
The kit had everything you needed. The installation was easy to do. Thanks for your tip in how to maintain an Rv.
I was very pleased that the replacement part physically fit perfect. Wiring it in was easy because of directions.
Needed the motor and controller to get my old RV steps working again. The kit was easy to use by removing the old parts and replacing with the new parts in less than 30 minutes. Totally happy with the results, working steps at less cost than replacing the full step package. Etrailer has been my “go to” for this and a Receiver package in the past. Their videos helped in determining the “do it yourself” level of effort and provided confidence in getting the installations done easily and correctly. Thanks!

A year later and still extremely happy with all etrailer products I’ve bought, installed and used. The step motor controller package has operated like new. As I mentioned last year, etrailer Is definitely my “go to” company for best products, price and help via “DIY” videos.
it was a very good experience my original order only came with half of what was supposed to be in it. I called customer service and explained that to the agent and they were very helpful and apologized for the mishap and they expidited the rest so I could leave on my trip.
Received parts in two days.
Excellent service.
This upgrade kit had enough torque to completely lift the stairs on my 2004 Bigfoot 3000MH24SL - the other upgrade kit, LC29VR, did not. It works great now. The only difference is the old steps “off” switch, to keep the stairs extended with opening and close the door, was an open circuit for “off” - new controls are an open circuit for “on”. I just reversed and relabeled the switch in the RV so it works as original.

Step motor still working great after a year - I expect it to last a long time.
