Pier & Anchor vs. Runner Systems Explained

Most manufactured homes in Bowie County sit on one of two support systems: a traditional pier-and-anchor setup, or a continuous runner system. Both are code-compliant when properly installed, but they behave very differently over time.

Pier-and-anchor

This is the most common setup on older mobile homes and many newer HUD-code homes. Individual pier stacks are placed along each I-beam, plus additional piers at critical points like corners and the marriage line on doubles. Auger-style ground anchors are then screwed into the soil and connected to the frame with steel straps.

Advantages: simple to inspect, easy to adjust piece by piece during a re-level, and cost-effective for a wide range of homes. Downside: each pier is a potential failure point, and Bowie County soil movement acts on each of them independently.

Continuous runner systems

Runner systems use long, continuous concrete or engineered beams under each I-beam of the home, distributing the load along a broader footprint. The home sits on the runners with shims or blocks and is still tied down with anchors.

Advantages: more even load distribution, fewer independent failure points, and often better performance on soft or uneven soils. Downside: repair work involves lifting sections of the home differently and is not always feasible on older setups without site changes.

What this means for re-leveling

On pier-and-anchor systems, most re-levels are pier-by-pier adjustments and occasional anchor re-tensioning. On runner systems, the work focuses more on shim rebuilds and confirming the runner has not developed uneven ground contact. Both are routine for experienced crews.
