Vibration & Rattle-Proofing for Vanlife Cargo Doors

Road buzz + thin sheet metal = the fastest way to murder a smart lock.

1) Damping Stack

• Closed-cell neoprene gasket behind escutcheon (1–2 mm) to decouple vibration.
• Butyl pads on inner door skin near latch pocket to kill panel ring.
• Felt tape on contact points that "tick" during bumps.

2) Shim & Strike Geometry

• Set strike depth for zero bind with both loaded and unloaded van weight.
• Use stainless shims to fine-tune latch engagement; no side-load on the bolt.

3) Fastener Discipline

• Blue threadlocker on all machine screws; paint-mark heads for drift detection.
• Use nyloc nuts or prevailing-torque fasteners where accessible.

4) Cable & Harness Anti-Chafe

• Edge grommets + braided sleeve; secure every 15–20 cm.
• Service loop with strain relief near moving points.

5) Real-Road Validation

1. Ten lock/unlock cycles parked.
2. Drive: speed bumps, cobbles, railroad crossing.
3. Repeat ten cycles. If tone changes or hesitation appears → recheck strike & screws.
