Are the 2013 voltage any better than the 2011/2012's ?

No issues with our 2012 3950 Epic. Very, very happy with it. The only thing I have to complain about is having 1 battery. It dosen't like to run the big fridge overnite. We were boondocking at the racetrack last weekend and I had to hook up the jumpers to start the genny in the am.

This is soon to be fixed though, 4 6v's and a xantrex inverter/charger are on my shopping list.

Oh, and the full paint sure turns heads!
