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

Got a 3600 back in February. So far just minor things. Took it in for a sewer flush out leak and also to put the awning brackets on for the rear awning. The black tank wouldn't fill completely but somewhere during a trip it resolved itself and has worked great since. Other than that nothing. No leaks in 1000 miles. I would look at another Voltage if I was in the market.
