We have had a 2015 Discovery 40G since last November. Spent first three months at dealer trying to get simple door railing fixed. This was dealer issue. However when finally got RV home, windshield leaked first rain. Then main slide leaked with water running across floor. Short story is windshield repaired, then windshield replaced, first major trip the gasket came off from both sides. Slide now has major leak with water pouring across floor. Slide wall coming unstapled and all wood screw covers popped off through out unit. Driver side view mirror arm came loose. Found 1 screw totally stripped at factory, 2nd screw head almost stripped. Then side view mirror almost came off arm. Duck tape very handy repair tool this trip for holding side view mirror on and windshield gasket in place. After 10 months of owning new 2015 Discovery, actually had possession 4 months with 6 weeks of that waiting for repairs. Engine has been fantastic but the construction on the rest has been a nightmare. Dealer refuses return of unit. So stuck with leaky, falling apart RV.
Very disappointed.
