We are on our 2nd Voltage 3200. Our first one was a 2011. The only problems we had with it was one of the motors for the main slide froze up over winter and was replaced by the dealer under warranty. We also added the second AC in the front bed room. Other than those major items, there were no problems with anything else.
We are now on our second 3200, as a 2015 model. We had one problem with it due to a problem at a campground, nothing to do with manufacturing. The manufacturer made some changes to various small items in the unit that we wanted from our first version. There are a couple of minor changes that they made that we are not happy with but can live with as no trailer is ever perfect.
