An excavation vehicle comprising:

• a debris body;
• a vacuum hose;
• a turret rotatably coupled to a top of the debris body and coupling the debris body and the vacuum hose in flow communication;
• and
• a boom assembly coupled to the turret and configured to at least partially support the vacuum hose, wherein the boom assembly comprises:
• a shoe configured to support at least a portion of the vacuum hose;
• a bracket that mounts to the turret;
• a first support member having a first end pivotably coupled to the bracket and an opposite second end;
• a second support member slidingly supported at least partially within the first support member;
• a third support member slidingly supported at least partially within the second support member, wherein the third support member includes a first end and an opposite second end, the shoe is fixedly coupled to the second end of the third support member with the second support member disposed at least partially between the second end of the first support member and the first end of the third support member;
• and
• a single hydraulic cylinder configured to extend and retract the shoe relative to the turret, wherein the hydraulic cylinder is supported on the first support member at a fixed position proximate the first end of the first support member and the third support member at a fixed position proximate the second end of the third support member, the hydraulic cylinder bypassing the second support member and configured to extend and retract the third support member relative to the first support member and at least partially indirectly drive movement of the second support member.
