We purchased a 2014 Grand Design Solitude 5th wheel in 15. We have had furnace go out 4 times!! Also lights flickering and if you turn on the lights in bath or bedroom the t.v. goes to no signal !! Called and talked to service mgr. To the 4th times on furnace and the Idaho r.v. lemon law. We brought it too them once and they said they fixed furnace only to have it go out in november. We have it winterized. N it is in our front yard. Service Mgr. I do not know how you keep your job!!!! Your a smartass big mouth whom has noo reason working with the public !! Attourney is next gooo bye
