We are on our second Voltage 3200. The first one was a 2011 with the Schwintek slide system. We had problems with that system right from the start. We loved the layout of the trailer and had no problems with anything except the slides. We picked up a 2015 3200 last year because we found that the Voltages now came with the cable mechanism for the slides and it also had additional features we wanted on our next RV. We have not had one bit of trouble with the current unit and expect to be keeping for many years.
Good luck with whatever you pick.
