A dealer may sell a home and coordinate several services, while a licensed setup contractor performs a defined installation scope. The names can appear in the same package without making their responsibilities identical.
Short answer: Use the signed documents and current license records to map roles. The dealer or salesperson should identify the legal seller, exact home, options, price, warranties, delivery or installation items included in the sales agreement, and any separately arranged provider. The setup contractor should identify the retained setup scope, applicable home and site documents, permit or inspection responsibilities, exclusions, corrections, completion evidence, and warranty for that work. Transport, foundation or masonry, electrical, plumbing, HVAC, utilities, grading, exterior access, skirting, inspections, and homeowner-supplied work may remain separate. Put each line under one named responsible party, one price treatment, one prerequisite, and one handoff record before comparing totals or assuming a bundled phrase covers the complete project.
