Interior fuse keeps blowing

I tried to discuss the cancellation of the warranty with the dealership. He had plenty to say but none of it regarding cancellation. Fraud in this situation is an understatement. This premium extended warranty was supposed to cover everything and was supposed to be available anywhere throughout the country. I decided to go out to the rv today, and seriously read all the paperwork (it was sitting on the rv kitchen table). The only 2 lights on the kitchen doesn't work and the main bedroom lights don't work. All other lights work. Don't get me wrong, I know it's an rv... and things are going to happen. But it's only sat in my driveway for 2 weeks and I only used it to driveway camping one night. Nothing is even turned on but the refrigerator. Which seems to be working fine. No other lights .. nothing...This time no fuses are showing red lights at all... and I checked each fuse, they are all good.... I would rather attempt to deal with these problems at home rather then out on the road. I love my new rv.... ive saved every dollar I could to take on this adventure, all while running my small farm here in Florida. Im just feeling overwhelmed with no help from the dealership, and a first time rv owner.
