New 2026 Grand Design Lineage Series M 25FW Motor Home Class C - Diesel
The Colton RV & Marine Advantage
No Hidden Fees RV and Boat Pricing:
The Colton RV & Marine Advantage (What Others Don’t Tell You).
Buying an RV or boat should feel exciting — not confusing. That’s why we created No Hidden Fees RV and Boat Pricing, part of the Colton Advantage.
Too often, shoppers fall in love with a unit online, only to be hit later with surprise fees like freight (getting the RV or boat to the dealership) or prep (the cost to clean, inspect, and ready the unit for you). These extra charges can add $1,000 to $10,000 to your total — and most dealers don’t mention them until it’s time to sign.
At Colton RV & Marine, we don’t believe in that. That’s why we created Colton Advantage Pricing — our commitment to transparent, all-inclusive pricing that respects your time and your budget.

Head to your local state park or across the states in this spacious coach. Once you arrive at your destination, you can prepare a meal with the full kitchen amenities, including a cooktop, microwave oven, and a refrigerator. The power theater seating provides a place to relax, or you can choose the optional booth dinette if you need additional sleeping space. A full bath will let you clean up after a day outdoors, and the 70" x 80" king bed within the full-wall slide is sure to bring comfort. This model also includes a pantry beside the theater seats for snacks and a bedroom wardrobe to keep your clothes wrinkle-free!

There is also a Blackout Package with black aluminum wheels, a Chromeout Package with chrome aluminum wheels, plus additional packages to enhance your travel experience!
Excellent experience. We arrived and Cory was waiting for us in the parking lot. He had the Alpha already set up for us to look at but was also willing to show us anything else we wanted to see. He was laid back and friendly and not pushy in any way. Everyone was super friendly. The store was cute and cozy and had a real nice family feel. It felt like the kind of place you'd like to work yourself - Christina
