Slide Out Mechanisms

Hello...Researching purchase of a new travel trailer for young family. Considering a handful of <30' models with bunks for the boys; Heartland Sundance, Mallard, Wilderness and Shadow Cruiser, Forest River Surveyor and Keystone Bullet.. From what I gather there are three primary slide out types, hydraulic, screw and cable. My question is about the type of mechanism each model above uses; which are less terrible than the others, and which to absolutely avoid? Thanks all! Doug

If I had my way, my next camper wouldn’t have a slide. Climbing up onto the roof to hose or sweep it off before bringing it in every time is good exercise but...

Yep. My next camper will NOT have Schwintek.

Power gear rack and pinion here also, I think its the best slide system on the market..


They were probably great until bought out by Lippert in 2014. It sometimes takes them a few years to cheapen and re-engineer a product they acquired to meet the business model. That business model is cheapen it to the point of failure shortly after the warranty period, and then overprice proprietary replacement parts by about 300% over what they're actually worth.

Schwintek- If the box itself and the opening are built correctly, and if the racks are installed correctly, and if they're aligned correctly, they're not all that bad. That's a lot of if's, especially in 2019 with the quick shoddy assembly and total lack or any QC or QA in RV factories. They're great for smaller slides such as wardrobe slides. Not so much for a 14' long full height slide with half a kitchen inside it. Think about it. Trying to move hundreds or close to a thousand pounds or more with two electric motors the size of the ones in a Harbor Freight Cordless Drill, and chances are good the motor in the HF drill may be better quality than the ones LCI outsourced. I shouldn't B&M. I've made quite a few bucks repairing Schwintek slides in the last 5 or so years. Probably 75% of the time its an alignment issue or other RV manufacturer install issue like lack of or not enough rollers.
Too many geezers, self appointed moderators, experts, and disappearing posts for me. Enjoy. How many times can the same thing be rehashed over and over?

Hard to avoid getting anything without the Lippert/Schwintek style these days. It is actually a reliable system IF the install was done properly although the weaker sidewall construction of TTs (compared to motorized RVs) makes getting one built right a little chancy. With this type of construction, routine maintenance is crucial BUT much easier than on others. YouTube has several good videos, some by the mfg. that show how simple it is. Those who do not lubricate with the recommended CRC Power Lube constitute the majority of those who have issues. These systems had problems with everything in the beginning but are quite reliable now. The nice thing about them is with both a top and bottom gear rack on each side of the slide, the slide is held in place much better going down the road and the need for a piece of broomstick wedged at the top when closed is no longer an issue. Recently the aluminum racks have begun to be replaced with steel ones which should make the mechanism even more durable.
Curious why you say that the majority of those who have issues are the ones that don't lubricate? My technician told me the majority of issues are due to low voltage.

Its easier to pull the pins on both sides, slide the small gear over and push the slide in and than reinstall the pins.

we have the cable system and its about 12 years old. I have replaced some of the cables and done some adjustments, its very easy to work on. I carry a couple spare cables kits and other parts just incase. I could easily change them on the road, the only thing that couldn't be fixed on the road is the motor if you didn't have a spare. you can also move the slide in with battery operated drill and a flex drive to fit your motor.
