Technical Spec for Mechanical Radio Product

I need a detailed technical specification for a mechanical product I've created, which is a ramp designed for RV. I already own and use my prototype. I know the materials used and I can provide pictures.

The technical spec should include:
- Comprehensive product description
- Materials and components used
- Functionality and operation details
- Dimensional and weight specifications
- Safety and compliance standards

Ideal skills and experience:
- Background in mechanical engineering or product design
- Experience in creating technical documentation
- Attention to detail and accuracy
