With 25+ trips in our 2013 Voltage 3950 we have not had a single issue resulting from the manufacturer or assembly. We, along with all of our friends and family that stay with us, love our Voltage. We definitely would purchase a Voltage again.
I have had a vent fan go out and a double pane window leak between the glass. Both were promptly replaced by the manufacturer of the products. Worst issue I saw with the build quality of our Voltage was a little saw dust in the air duct. I did replace the factory tires after about 18 months, with Sailun G-rated tires, which I've been very impressed with.
I find it interesting that the negative posts to this thread are not qualified to give a valid opinion since they don't own a Voltage and as such, have no experience to base a judgment on.
If they used this same mentality when evaluating their purchase of a tow vehicle, based upon the negative posts on the Powerstroke.org forum, they would not purchased a powerchoke.
