We have the smallish kitchen slide on our travel trailer. I do find because it is at least 350 lbs of mass that a little trick seems to ease the strain on the motors very slightly.
What I have found is that by having the slide ever so slightly tilted down it slides out a little easier and seems to take some of the strain off the mechanism. Then before sliding back in for travel I gently roll up to slightly higher than level on the slide side and the slide motors again run with a little less strain.
I do not mean using radical differences in tilt to facilitate movement, no more than a 2 degree up or 1 degree down.
It does add and extra complication to setting up but it might be worth it as long as the slide rollers and tracks are very well cared for as ours are.
The reason why I do this is because the stabilizers are not great at all at and when I slide out perfectly level the heavy mass of a kitchen slide moved out does tend to tilted down the trailer on the slide out side.
I just cleaned the tracks for this season of camping and am starting the de wintering process. I see no difference in the wear on the gears or the tracks they seem fine. After cleaning the tracks and applying a new coating of white grease it is being evenly spread by the gears and the slide is working better than without grinding sounds or too much strain that cause can cause a motor index register fault or damaged drive gears and overheated motors.
Anyone else use this method to reduce wear on the mechanism?
