I know there were issues with the slides when the Voltage first came out. It seems like many of these were related to large slide outs, maybe larger than the Schwintek system is capable of handling. ...
I bought a lightly used 2014 3305 and this was the concern I feared most. Making sure I am level and only had one night out so far. Fingers crossed. The 2016 I looked at had cables but the slides looked to run on the same track.
