Start with what must fit
Measure vehicles, RVs, equipment and stored items, including height and roof-mounted accessories.
Plan usable space
Allow room for door swing, slide-outs, walkways, workbenches and equipment movement.
Think ahead
Future vehicles, storage and business growth can justify extra width, length or height now.
Engineering, warranty, permitting and installation requirements can vary by project. Final written order documents and applicable local requirements control.
