What Is the Cost of a Grand Design Lineage
M 25FW
Standard Run MSRP $195,401
The Manufacturer’s Suggested Retail Price (MSRP) is the price that the manufacturer recommends for their product. RV dealerships use this figure as a starting point to set their final prices. While some dealer prices may be higher than the MSRP, others might be lower.
The Minimum Advertised Price (MAP) is the lowest price a manufacturer permits a retailer to publicly display for their product. You might see phrases like “price too low to show” on some websites, indicating that the dealership’s price is lower than the MAP, but they can’t advertise it without direct contact.
For Grand Design RVs, the advertised price must match their MSRP, meaning dealers must display this price even if they can offer a lower one. By contacting a dealership directly, you can often get a more precise and potentially lower estimate.
