But reading the problems here with bigger slides makes me nervous for sure. We bought the rig about 1 month ago and I have been trying every system while its been parked at the house. We will take it on its first run in late March.

So far I have moved the slides about 10 times without any problems. One thing that I do follow from the owners manual - which I never ever did in any prior RV is that when RETRACTING a slide - extend it first and hold the command button for 8+ seconds, then retract it. Conversely, if EXTENDING a slide, retract it first and hold the command button and then extend it.

This is supposed to re-sync the motors after each hectare/extend.

And in all cases when you get the slide fully retracted or extended, hold the command button for well after the motors stop.

I also have the 3 Trax system on this model. It will be interesting how this all works out. But reading the problems/fixes here gives me hope that if I have the problems then I can get them fixed.

Thanks to all for sharing the problems with slides.

We have a 2017 Miramar 34.1 and the slides have always worked effectively. Sometimes they might get out of sync and the the procedure that is provided to fix that works. You are right that you should hold the extend or retract for a few seconds after full extension or retraction to keep the motors synced. Sometimes when first extending the slide outs you might find that they don’t respond initially. If that happens then hold the retract button for a couple seconds and then go to extend. Another thing to invest in is a can of CRC lube to spray on the tracks periodically.
