Are all equal.. NO they are not
Some are Cable Cars (Accu-slide) Look for, when extended, two cables on the "FRONT' and "REAR" (Directions refer to when going down the road) of the slide
Some are Rack and Pinion systems (Power gear) Look for TOOTHED rails under the slideout
Some are hydraulic
Swintek uses a metal strip with a serpentine (Wavy) line or slot on the front and back of the slide out.
What to look for.. Not sure.. What I have observed.
Power gear and Accuslide (What I have) use the same basic type of controller. this unit senses current to the motor and when it increases it shuts the thing off.. I've had issues with needing multiply attempts to get the Accu-Slides in and out.. Works though. Power gear I've not had that problem but the controller just failed.. I'm working on it.
The Accu slides.. if the cable breaks and the broken end pulls in it is a WITCH to run the new cable. but doable. (I did) easier if you get it before the broken end vaishes
Finally if you need to "OVERRIDE" the slide manually (IE: Control failure)
Accu-slide.. Drill with a flexible hex tool (Drill;/Screwdrive) extension
Power gear.. Ideally a 3/4 inch rachet wrinch but .. Well It's a job.
