Chassis-Aware Design

Accessories are designed specifically for RV frame structure and load paths.

Safe Load Distribution

Fabrication considers weight, stress, and dynamic forces during travel.

Purpose-Built Solutions

No universal brackets or improvised frame attachments.

Common Problems We Fix

Frame-mounted accessories must account for RV movement, frame flex, and long-term stress—areas where generic solutions often fail.

Accessories requiring structural support

Items that cannot be safely mounted to walls or body panels.

Aftermarket solutions not designed for RV frames

Universal mounts often ignore RV chassis design.

Improper frame attachments causing stress or cracking

Incorrect mounting points can damage the frame over time.

Custom layouts or non-standard accessories

Unique installations require purpose-built fabrication.

Frequently Asked Questions​

Frame-mounted accessory fabrication involves designing and installing custom accessories that are securely attached directly to the RV’s frame rather than body panels or thin structural surfaces.
Frame mounting provides greater strength, load capacity, and vibration resistance, reducing the risk of cracking, loosening, or long-term structural damage.
Common frame-mounted accessories include storage boxes, bike or cargo racks, generators, spare tire carriers, steps, skid plates, and custom equipment mounts.
Yes. When properly fabricated and installed, frame-mounted accessories are designed to safely support heavier loads than body-mounted alternatives.
Yes. Each fabrication is customized based on the RV’s frame design, weight limits, accessory purpose, and clearance requirements.
Properly designed installations account for weight distribution and balance, helping maintain safe handling and towing performance.
Yes. Direct frame attachment minimizes movement and vibration, reducing noise and wear compared to flexible body mounts.
Some installations require welding, while others use reinforced bolt-on designs. The method depends on load requirements and frame construction.
It depends on the manufacturer and installation method. Proper fabrication minimizes risk, and inspections help ensure compatibility with existing warranties.
Most fabrication projects are completed within one to several days, depending on complexity and customization requirements.
Yes. Many fabrications are designed with future removal, upgrades, or accessory changes in mind.
