A seal for living quarters having main living area walls and a main living area floor defining a main living area, said main living area floor having a lateral edge, an aperture in one of said main living area walls slidably receiving a slide out room having slide out room walls and a second floor defining an auxiliary living space, said slide out room capable of movement between a retracted and an extended position, said second floor adapted for slidably overlaying said main living area floor and separated therefrom, said seal characterized by: a floor portion formed from a single member, and a splash portion formed from a single member; the floor portion comprising an inward flange and an outward flange, said inward flange having a lower surface and an upper surface, said outward flange having a lower surface and an upper surface, said lower surface of said outward flange being substantially parallel with said lower surface of said inward flange, a wear bar integrally attached between said inward flange and said outward flange, said wear bar having an outward upright wall extending upwardly from said outward flange at a first terminal end of said outward flange in a direction opposite said lower surface of said outward flange, said outward upright wall terminating at an outer terminal end of a top wall, said wear bar having an inward upright wall extending upwardly from said inward flange at a first terminal end of said inward flange in a direction opposite said lower surface of said inward flange, said inward upright wall terminating at an inner terminal end of said top wall, said top wall being spaced from said inward and outward flanges (36/38), an exterior leg attached at a second terminal end of said outer flange at a point intermediate to its ends, said exterior leg having a lower portion extending in an opposite direction of said wear bar below said lower surfaces (37/39) of said inner and outer flanges (36/38) and said lower portion being substantially perpendicular to said outer flange, said exterior leg including an upper portion being located above said outer flange said upper portion being more flexible than said lower portion; the splash portion being generally L-shaped and comprising: amounting leg and a sealing leg that is substantially perpendicular to said mounting leg, said sealing leg having a portion nearest a distal end of said sealing leg being more flexible than said mounting leg; and said lower portion of said exterior leg adapted to overlay a portion of said mounting leg of said splash portion, a portion of said upper portion and said wear bar adapted to contact a lower surface of said second floor. a floor portion formed from a single member, and a splash portion formed from a single member; the floor portion comprising an inward flange and an outward flange, said inward flange having a lower surface and an upper surface, said outward flange having a lower surface and an upper surface, said lower surface of said outward flange being substantially parallel with said lower surface of said inward flange, a wear bar integrally attached between said inward flange and said outward flange, said wear bar having an outward upright wall extending upwardly from said outward flange at a first terminal end of said outward flange in a direction opposite said lower surface of said outward flange, said outward upright wall terminating at an outer terminal end of a top wall, said wear bar having an inward upright wall extending upwardly from said inward flange at a first terminal end of said inward flange in a direction opposite said lower surface of said inward flange, said inward upright wall terminating at an inner terminal end of said top wall, said top wall being spaced from said inward and outward flanges (36/38), an exterior leg attached at a second terminal end of said outer flange at a point intermediate to its ends, said exterior leg having a lower portion extending in an opposite direction of said wear bar below said lower surfaces (37/39) of said inner and outer flanges (36/38) and said lower portion being substantially perpendicular to said outer flange, said exterior leg including an upper portion being located above said outer flange said upper portion being more flexible than said lower portion; the splash portion being generally L-shaped and comprising: amounting leg and a sealing leg that is substantially perpendicular to said mounting leg, said sealing leg having a portion nearest a distal end of said sealing leg being more flexible than said mounting leg; and said lower portion of said exterior leg adapted to overlay a portion of said mounting leg of said splash portion, a portion of said upper portion and said wear bar adapted to contact a lower surface of said second floor.
