What is the most reliable slide system?

electric , hydraulic. I would like to know especially for large slides , what type of mechanism works best? I do not mind servicing, but do not want to get stuck with an open slide.

Well the Newmar electric motors driving the big cog wheels has been simple and reliable so far.

The 2016 and newer Newmarís have gone to a HWH hydraulic system so that the slides can be totally flat when deployed.

I think either of these is better than the other systems I have heard about.

The most reliable slide is no slide at all.

I may be wrong but the HWH slides are only on the diesel lines. Gasserís still use electric motors and are very sturdy.

All depends
The slim rack electric is the easiest to fix.
HWH is the hardest to fix.
They are all pretty reliable considering the numbers in service.
But, when they don’t work, it’s a disaster

Our previous 2014 Georgetown 378XL (Ford F53 Gas Chassis) had hydraulic slides and jacks.

Yes, you are right. I was simply comparing two different types of systems.

Hydraulic slides are used on the biggest and heaviest slides for a reason. While the system is straightforward, it isn’t necessarily easy to fix these days because of parts shortages. It can handle heavy weights though. Schwintech electric slides are popular, but I think they work best in small slides. We have had to get one of ours worked on already. Not hard to repair, but a pain. The Vroom electric slides are gaining a lot of traction because they are more robust and have bigger motors. I may eventually replace our Schwintech slide in the bedroom/bath with that model.

Had a 06 KSDP with the flat floor slide outs, which Newmar invented. BTW Newmar is the one that invented the slide out.

I had my rails and motors replaced on the kitchen slide. All rollers, blocks and motors in place. Tested it 5 times before leaving the shop , went camping worked good. Came home and got ready to go again 2 weeks later, slide would not come out. Over rode the controller thinking it had to be re calibrated with the motors - went out part way and bottom left would only go part way. Checked the gap between rv wall and slide thinking now that when Tiffin cut out the hole for the slide, they may have cut the hole too large and allow the whole slide to move when I was traveling and that could be the reason that it shifted off the motor? What is the structural warranty on these units? Mine is a 2020.

^ This!
Slides are great for adding room to the inside of your RV but they add weight, weaken the entire box and fail all too frequently due to sloppy engineering and low budget constraints.

Iíve had Schwintec sides on a Class C and wouldnít recommend them. I now have Power Gear electric Slim Rack on two slides and Power Gear Under Floor on a living room slide. I assume itís electric, too, though it seems to work much more smoothly.

It seems the smaller the slide room the better no mater the brand.

No, "no slide at all" by definition is not a slide.

As to the real answer, I definitely don't have the data to answer beyond anything but anecdotes, but I do have schwintek issues (small slide), and have never had a hydraulic issue.

I wonder of Vrooms $olution will gain traction.

Vrooms system seems a very good solution and looks carefully crafted and installed. For it to really succeed long term it should be adopted by a RV manufacturer. As an aftermarket fix for bad Schwintec slides they can’t handle all the demand.

In some ways the Power Gear Slim Rack is similar to the Vroom system.

They all have their issues, although our HWH single super slide/leveling system has performed well. I will say this, a friend has a Lippert hydraulic leveling/multi slide system on their newer fiver and it's been an absolute nightmare. Multiple blown hoses, bad hydraulic pump and two leaking Jack cylinders in two years since new. I will say Lippert customer service has been good, but unsuccessful in resolving his recurring issues. Constantly blowing 200a fuses, sounds like it's deadheading at times, lift legs work only about half the time. He carries an assortment of bottle jacks and drain pans every trip out.
It's to the point he wants to get rid of it.
