11 . The material collection vehicle of claim 1 , said bearing seal comprising:

a bearing; and

one or more bearing clamps configured for securing said bearing against the second boom section to provide for sealing engagement between the bearing and said second boom section.

12 . The material collection vehicle of claim 11 wherein the one or more bearing clamps provide for sealing engagement with the first boom section;

wherein the bearing comprises a plurality of pieces of a deformable material wrapped about the second boom section, the plurality of pieces being positioned about the second boom section to form one or more gaps in an absence of pressure provided by the one or more bearing clamps, the plurality of pieces configured to deform to fill in the one or more gaps when said one or more bearing clamps are tightened around the bearing.

13 . A mounting system configured for mounting a boom assembly to a material collection vehicle comprising:

a turret including a turret housing enclosing a turret chamber; and

a joint including a joint housing shaped to form an opening providing for fluid communication along a fluid pathway including said turret chamber, the joint housing being pinned to the turret housing, the joint being sealingly coupled to said turret using one or more seal packings, the one or more seal packings forming a seal along a boundary between said joint and said turret;

wherein the seal maintains sealing engagement between the turret and the joint over a range of motion of the joint;

wherein said joint comprises a knuckle joint; and

wherein the joint housing comprises a curved surface upon which at least one of said one or more seal packings is slidably engaged when said joint and said turret are sealingly coupled together.

14 . The mounting system of claim 13 wherein said curved surface is formed on a generally C-shaped bracket including a curved upper surface and a curved lower surface, a top side of said seal being slidably engaged with said upper surface and a bottom side of said seal being slidably engaged with said lower surface.

15 . A material collection vehicle comprising:

a telescopically extendable boom assembly including:

a first boom section and a second boom section, the second boom section being configured for nested engagement with said first boom section;

a mounting system configured for connecting said boom assembly to a body of said material collection vehicle, the mounting system including:

a joint including a joint housing shaped to form an opening disposed along a sealed path of fluid communication extending from an interior portion of said boom assembly to said vehicle body through said joint; and

a turret coupled to the joint, the turret including a turret housing; and

an actuator connected to the turret housing and the boom assembly;

the joint comprising a knuckle joint and being sealingly coupled to the turret using one or more seal packings, the one or more seal packings forming a seal along a boundary between said joint and said turret;

wherein the seal maintains sealing engagement between the turret and the knuckle joint over a range of motion of the knuckle joint;

wherein at least a portion of said seal is slidably engaged with said joint housing along a curved surface of said joint housing.

16 . A mounting system configured for mounting a boom assembly to a material collection vehicle comprising:

a turret including a turret housing enclosing a turret chamber; and

a joint including a joint housing shaped to form an opening providing for fluid communication along a fluid pathway including said turret chamber, the joint being sealingly coupled to said turret using one or more seal packings, the one or more seal packings forming a seal along a boundary between said joint and said turret;
