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

We have had our 2012 3905 about 6 weeks now, traveled about 1500 miles, 4 days boondocking, 4 days in a park. So far only a few small items. Dutchman is very nice and cooperative so far, dealers are another situation. I knew I would be an orphan buying this unit so far from home but will deal with the dealer thing since I paid 52k for it new. Trying to backdoor my way into service with extended service plan. We are very happy with this TH so far.
