Warranty Reduction & Root Cause Engineering
When structural, thermal, or suspension failures happen in the field, isolating the true physical root cause is critical to preventing brand erosion. Caliber combines advanced simulation, CAD structural stress history, load path reconstruction, and metallurgy failure engineering to trace why assemblies failed—not just where they fractured.
Our cross-disciplinary engineering group directly supports your teams to:
✔ Investigate field warranty patterns
✔ Prioritize cost-effective fixes
✔ Validate layout design changes
✔ Eliminate repeat assembly issues
✔ Evaluate supplier quality specs
✔ Drive iterative product upgrades
Automotive Rigor Applied
We translate years of automotive fatigue, structural tolerance stack-up analysis, and vibration history to the lightweight, rapid manufacturing processes of the RV industry.
Regulatory Action Support
Deploy physics-backed simulation proof packages to clarify structural behavior under investigated operational constraints.NHTSA Investigation & Legal Technical Support
When an audit, unexpected defect trend, or formal agency investigation begins, having ironclad engineering documentation is vital. Caliber supplies the simulation foundation and analytical trace profiles necessary to address questions from the Office of Defects Investigation (ODI) or support compliance teams.
Our regulatory validation capabilities feature:
✔ Recall structural validations and technical path checking
✔ Office of Defects Investigation (ODI) data packet responses
✔ Rigorous engineering simulation reports & load reconstructions
✔ FMVSS objective assessment engineering files
✔ Clear expert reporting and deep root cause validation documents

Proven Engineering Experience
Structural Engineering
Finite element analysis for RV frame strength, fatigue life, and durability under road load conditions. We validate sidewalls, roof panels, floor systems, and hitches against real-world load cycles — before a single prototype is cut.

NVH Analysis
Noise, vibration, and harshness simulation to identify resonance modes, reduce cabin noise, and improve ride quality. Modal analysis pinpoints structural weak points before they generate warranty events in the field.
Vehicle Dynamics
Multi-body dynamics simulation to evaluate ride, handling, roll stability, and towing behavior. Critical for towable trailer certification and motorhome platform validation, especially under NHTSA scrutiny.
Aerodynamic Performance (CFD)
Computational fluid dynamics analysis to reduce aerodynamic drag on Class A, B, C motorhomes and 5th wheels. Lower drag translates to better fuel economy, reduced buffeting at highway speeds, and improved towing stability.

HVAC & Cabin Thermal Comfort
Thermal CFD simulation to evaluate A/C performance, airflow distribution, insulation effectiveness, and solar heat gain in RV cabins. We optimize comfort across extreme environments — from desert sun to mountain cold.
Read Case Study →
Powertrain Simulation
Engine load, drivetrain stress, and towing performance simulation for motorhome platforms and tow vehicle pairings. We analyze powertrain loads under grade, GVW, and GAWR conditions to prevent mechanical failures before they reach customers.

Towing Stability Analysis
Dynamic analysis of 5th wheel, gooseneck, and conventional hitch configurations under yaw, sway, and emergency braking. We model trailer-tow interactions to eliminate dangerous sway and optimize weight distribution hitch-to-tongue.
New Suspension Selection & Design
Kinematics and compliance analysis for RV trailer suspension systems — leaf spring, torsion axle, air ride, and independent configurations. We select and tune systems for optimal load capacity, ride quality, and fatigue longevity.
Frame Redesign & Optimization
Digital engineering-driven RV frame redesign: topology optimization, cross-member placement, rail gauge selection, and structural connection point analysis. We help OEMs reduce weight without compromising structural integrity or increasing cost.
5th Wheel Hitch & Pinbox Redesign
Structural validation and redesign of 5th wheel coupling systems including king pin boxes, upper coupler plates, and aftermarket hitch replacements. We test fatigue under realistic towing cycles and evaluate failure modes before field exposure.
Sidewall & Roof Panel Design
Composite and laminate panel structural analysis for RV sidewalls, roofs, and slide-out structures. We evaluate bonded panel integrity, snow load capacity, wind pressure resistance, and thermal bridging in wall assemblies.
Alternative Materials Investigation
Investigation of aluminum, high-strength steel, fiber-reinforced composites, and engineered wood alternatives for RV structural applications. We model material substitutions to validate performance parity while hitting aggressive weight and cost targets.
