Delivery price is a route-and-responsibility question, not only a mileage question. Define the home, origin, destination, sections, permitted route, site entrance, staging, placement, and handoff before comparing charges.
Short answer: Manufactured-home delivery and transport cost can reflect distance, section count and dimensions, permits, escorts, route surveys, road restrictions, bridges, overhead clearance, traffic control, tolls, fuel, driver and equipment time, origin preparation, destination access, staging, special handling or crane needs, placement limits, weather and delay terms, return trips, site or road protection, damage responsibility, and work by others. New-home freight, delivery to the property, placement on the site, and moving an existing home are different scopes unless the documents combine them explicitly.
