We now have 3 camping trips on our new 179 (June, 2015) each for 3 days and about 200 miles on each trip with no major issues. However I noticed that when the slider was in the out position the panel under the refrigerator would bulge at the bottom. After removing the the panel I found that the tie wraps to the slider power cables had been cut and that the cables would hang down low enough to get caught on the small kick plate that is behind the larger panel causing the larger panel to be forced out at the bottom. I replaced the ties and adjusted the cables, it took about 3 tries to get them so that they wouldn't catch but also would not be too tight with the slider in. Not sure if the cables were cut at the factory or at the dealer I cant imagine why any one would cut them.
Other than the blown reverse polarity fuses on the converter which I described in a post in the dealers forum we are very happy with out 179. Next trip is Boston to Rocky Mountain NP, Grand Tetons NP and Yellowstone we should be able to break some things on that trip.
