Hello ApplicationError,

The Gulfstream Supernovas have some issues just like any other RV. However if you do a lot of dry camping the fresh water capacity, grey water and black water capacities are hard to beat. The international chassis handle the weight very well but can be rough (very rough) riding unless equipped with a rear air ride system. Many people complain about interior cab noise however I had a Super C built on the Kodiak Chassis and a Duramax and noise was similar. Engine power is good on flat ground but could use some more torque when climbing long hills - I have the 40' 6400 so it is the heaviest of the Supernovas. Some people do not like the engine as it is a close cousin to the Ford 6.0. I feel its a good engine if you do a few modifications to it. Interior build quality is good in some areas and not so good in other areas, I feel its on par for the price level of these RV's. I take my RV on gravel roads on a regular bases and the 22.5 tires/wheels do very well on the gravel roads. Best I can tell Gulfstream manufactured the Supernovas from late 2007 through 2012. However it appears most of the units were built in 2007 and 2008. I have only seen a handful of 2010, one 2011, and no 2012's. One issue I have with my 2010 6400 is the large wall slide. The 2010 and up Supernovas used a cable mechanism for both slides and I have never been able to get my wall slide to work as good as I would like. The slide goes in and out but not as smooth as I would like. I installed a higher torque motor on the slide and it works a little better, but still not as good as I would like. I need to look at the amp draw, but I don't have a DC clamp on amp meter.

PM me if you have questions.
