I need a full structural design for a customizable trailer that can alternate between carrying horses, general cargo, and a motorcycle. The core requirement is a modular frame and body that lets me install or remove interior and exterior components quickly, without specialized tools, so the same chassis serves multiple roles on short notice. Key elements to accommodate: • Removable partitions for safely transporting one or two horses. • Bolt-on / slide-in motorcycle mounts that lock the bike securely to the deck. • A detachable top section (roof and side panels) that can be lifted off and nested for compact storage when I only need a flat-bed or open cargo configuration. . Easy to dismantle the whole trailer for storage. I am open to material suggestions—steel, aluminum, or a hybrid—so long as you provide weight, strength, and cost comparisons. Please include standard lighting, brake, and suspension considerations that comply with typical North American DOT regulations, and leave space for optional add-ons such as ramps or extra ventilation if I decide to upgrade later. Deliverables I expect: 1. 3D CAD model (SolidWorks or similar) with all assemblies and exploded views. 2. Detailed fabrication drawings with dimensions, weld symbols, and material specs. 3. Basic structural calculations or FEA showing the design meets safe load limits for the three use-cases. 4. A short setup guide illustrating how each modular piece is installed or removed. I will review drafts, provide quick feedback, and aim to move to fabrication as soon as the design passes my local registration checks. Let me know your timeline and any questions you have about clearances, axle rating, or hitch style so we can get started right away.

Hello, I'm Serj, a mechanical design engineer based in Germany with 4+ years in vehicle and trailer structural design — agricultural, equestrian, and transport. My clients include Rheinmetall, Airbus, Atlas Elektronik, and other industrial leaders, which means I'm used to meeting strict engineering and documentation standards. My approach: hybrid galvanized steel chassis + aluminum panels/roof for the best strength-to-weight ratio. All modular components (horse partitions, motorcycle mounts, roof/sides) use a bolt-on / slide-and-pin interface — no special tools, under 30 min to reconfigure. Deliverables: SolidWorks 3D assembly + exploded views Fabrication drawings (GD&T, weld symbols, BOM) Structural calcs + FEA for all three load cases Visual setup guide (PDF) Timeline: 3–4 weeks to first full draft, with review checkpoints. I'm familiar with DOT/FMVSS 108 requirements — lighting, brakes, axle ratings — so your registration check should go smoothly. Quick questions: — Preferred GVW and tongue weight? — Ball hitch or pintle? Axle config (single/tandem)? — Any storage height/length limits? Looking forward to it! Best, Serj C. — Mechanical Design Engineer, Germany

Hi, I reviewed your requirement and this is a structural and modular design problem, not just a trailer model. If the frame and connections aren’t planned right, it won’t stay practical across all three use cases. I’ll design a modular chassis with removable sections, secure mounts, and clean connection points so transitions between horse, cargo, and motorcycle setups stay fast and tool-free. Material selection will be justified with weight, strength, and cost trade-offs, along with DOT-compliant lighting, braking, and suspension considerations. You’ll get a full CAD assembly, fabrication drawings, and basic structural validation so it’s ready for real-world build and approval. The focus will be durability, ease of disassembly, and long-term usability without redesign. Best regards, Muskan
