Butt joint for trailer side wall

1. A sidewall of a trailer comprising:

a side panel;

an outer member;

a base rail having an upper portion offset from a lower portion, an outer surface of said upper portion of said base rail is generally parallel to and spaced from said inner surface of said outer member, wherein the outer member is coupled to and engaged with (i) the side panel and (ii) the lower portion of the base rail;

a channel defined by an outer surface of said upper portion of said base rail and said inner surface of said outer member, said side panel being positioned within said channel; and

said lower portion of said base rail is positioned beneath said channel,

wherein the outer member includes a first portion engaged with the side panel and a second portion engaged with the lower portion of the base rail, and wherein the first and second portions of the outer member each define respective first and second inner planar surfaces that are generally vertically-aligned with each other.

2. A sidewall as defined in claim 1 , wherein said outer member further includes a rail.

3. A sidewall as defined in claim 1 , wherein said outer member includes a protrusion positioned above said lower portion of said base rail and extending inwardly.

4. A sidewall as defined in claim 3 , wherein said protrusion extends to an outer surface of said base rail.

5. A sidewall as defined in claim 3 , wherein said outer member further includes an adhesive cavity.

6. A sidewall as defined in claim 3 , wherein said outer member is secured to said base rail using fasteners.

7. A sidewall as defined in claim 3 , wherein said outer member is secured to said base rail using adhesive.

8. A sidewall as defined in claim 1 , wherein an outer surface of the lower portion of the base rail is generally aligned with an outer surface of the side panel.

9. A sidewall as defined in claim 1 , wherein substantially all of the lower portion of the base rail is beneath the side panel.

10. A sidewall as defined in claim 5 , wherein the cavity is formed in the first portion of the outer member.

11. A sidewall as defined in claim 1 , wherein a centerline of the lower portion of the base rail is positioned outwardly from a centerline of the side panel.

12. A sidewall of a trailer comprising:

a side panel;

an outer member;

a base rail having an upper portion offset from a lower portion, an outer surface of the upper portion of the base rail is generally parallel to and spaced from the inner surface of the outer member, wherein the outer member is coupled to and engaged with (i) the side panel and (ii) the lower portion of the base rail; and

a channel defined by an outer surface of the upper portion of the base rail and the inner surface of the outer member, the side panel being positioned within the channel,

wherein the base rail is positioned beneath the channel,

wherein the outer member includes a first portion engaged with the side panel and a second portion engaged with the lower portion of the base rail, and wherein the first and second portions of the outer member each define respective first and second inner planar surfaces that are generally vertically-aligned with each other,

wherein an outer surface of the lower portion of the base rail is generally aligned with an outer surface of the side panel and a centerline of the lower portion of the base rail is positioned outwardly from a centerline of the side panel, and

wherein the first portion of the outer member includes a cavity having adhesive therein.
