Grand Design Breaks Into the Motorized Market With the Lineage Line of Motorhomes

Grand Design has long been known for its towables, but in June of 2024 they officially announced their first product in the motorized RV market. Since that time, they’ve expanded the Lineage series even further.

In this post, we’re taking an in-depth look at the Grand Design Lineage 25FW, a Class C RV with the distinction of being Grand Design’s very first motorhome ever! We’ll also give you sneak peak at their second and third motorized rigs, a four-wheel-drive capable Super C RV and a pretty slick AWD “Adventure Van”.

What Is the Grand Design Lineage Series M?

Built on the Mercedes Benz 4500 Sprinter chassis with a twin-turbo, 4-cylinder engine, the Lineage (Series M) was Grand Design’s first foray into the world of motorhomes, followed by the Lineage Series F (a Super C RV with 4×4 capability), and the Lineage Series VT (an AWD adventure van).

For their first foray into the motorized RV market, the Series M, Grand Design chose to go with the 4500 rather than the typical 3500 to give RVers an extra 1,000 pounds of GVWR (for a total of 12,125 lbs). This made it possible for Grand Design to stay away from using cheaper composite materials in the build to save on weight.

Grand Design Recreational Vehicles is well-known for its series of towables including travel trailers, 5th wheels, and toy haulers (for more information on each of these types of towables, see our posts on travel trailers vs 5th wheels and toy hauler motorhomes). They first stepped into the world of motorized RVs with a Class C model, the 2025 Grand Design Lineage 25FW (to get a good sense of the differences between the various classes of RVs, we suggest taking a look at our post on RV classes).

The Lineage 25FW is a 2025 model with a European-inspired flair. It’s part of the “M Series” because it’s built on the Mercedes Sprinter chassis. All of the future motorhomes from Grand Design will be known as “Lineage” as well, (like the F and VT Series rigs we’ll talk about shortly), but will be distinguished by series depending on the chassis on which they’re built.

Let’s first take a look at what the original Grand Design Lineage 25FW, a Class C RV, offers to RVers.

Class C RV

The Grand Design Lineage 25FW is a Class C rig, which makes it a part of one of the most popular classes of RV right from the start. The Class C RV is essentially the middle child of motorized RVs, sitting squarely between the Class A and Class B rigs in size.

You can generally recognize Class C RVs by the “cabover” that sits above the driver and front passenger area. This space usually includes a large bed (which is a popular sleeping area for kids) or an entertainment center and storage area, depending on the floorplan.

Class C motorhomes are a great combination of features: ease of driving, plenty of sleeping space, and modest cost of operation. Also, because the Class C is motorized, no secondary vehicle is required to tow it. Moreover, the modest size of (many) Class C rigs compared to Class A RVs makes them a little more errand-friendly, so you really don’t need a “toad” (towed car) to get around town.

Relatively Easy to Drive

Class C rigs can vary widely in length, from as little as about 21′ to as long as 45′, and the Grand Design Lineage 25FW falls in at a length of 25′ 8″. This makes it relatively easy to maneuver, even for those new to driving RVs. In fact, Class C RVs are the most popular motorhomes to rent due to the ease of driving and parking, in combination with the amount of space offered inside.

Optional Full-Body Paint

Full-body paint is an option that was once the purview of more expensive Class A motorhomes, though it has become more and more available in recent years. The Grand Design Lineage M Series offers this as an option. Full-body paint is desireable for its ability to offer a significantly longer lifespan than typical RV decals. Not only is full-body paint more likely to hold up over time, but it will also boost the rig’s resale value down the road.

Rear King-Sized Bed

The Grand Design Lineage 25FW Class C motorhome includes the first rear king-sized bed ever offered in the Sprinter Class C market. This is a great feature for many couples who enjoy the comfort of an expansive bed, and this can even be great for parents of young children who like to “co-sleep” (especially when camping in unfamiliar places).

Improved Chassis Stability

The M series of Grand Design’s Lineage offers improved chassis stability right out of the gate with outriggers and a “halo support” structure. Both of these structural additions help to increase the strength and rigidity of the RV’s frame & chassis, while also improving the ride comfort and overall durability of the entire coach.

Deep, Full-Wall Slide-Out

Grand Design steps into the motorized RV market offering the deepest full-wall slide available on a Sprinter Class C. This allows for an exceptional amount of space in such a mall RV.

Advanced Heating and AC Distribution

Heating in the Lineage 25FW is distributed by vents in the cabinets/sidewalls instead of the floor. This may seem like a small detail, but it offers several noticeable advantages:

1. No worrying about small items falling into the vents
2. No need to be careful to avoid stepping on the vents
3. No concern(s) about any items (like your washable area rugs) covering vents

In addition, the advanced air conditioning system has slot diffusers (instead of traditional vents) that reduce noise while improving air distribution. All of this is designed to ensure that the interior of the RV is maintained at a comfortable temperature, regardless of what’s going on outside.

Standard 3,600W Propane Generator

The Grand Design Lineage Series M comes standard with a 3,600W propane generator to power the rig when you’re off-grid, drawing from your propane reserves as opposed to traditional generators that can deplete your rig’s fuel supply.

You can also upgrade to their Power Package which includes 600W of solar panels, two Lithionics lithium-ion batteries (stored under the entry steps), and a secondary alternator. Note that you’ll need to run the generator to run the AC and/or microwave off-grid.

AFTERMARKET UPGRADE: Need even more power for your off-grid adventures? Consider going with a professionally-installed solar & lithium battery system like the one we had installed by MYT Solar.

Grand Design Lineage 25FW Floorplan

The deep street-side slide opens up a lot of space in such a small RV, making the interior feel quite open and roomy. The 70″ x 80″ RV King bed is a rarity in Sprinter-based Class C RVs, offering plenty of comfortable space to sleep. The 25FW is the first (of many) floorplans to come in the Lineage:

How Much Does the Grand Design Lineage 25FW Cost?

The manufacturer’s suggested retail price of the Lineage 25FW is $228,776.

For comparable (in terms of relative size and amenities) Class C RVs in the space we can look back at our post on 7 of the best Class C RVs under 30′. Using 2025 models to offer a bit of a comparison in terms of cost, we can look at the pricing for the following Class C rigs for comparison:

• 2025 Minnie Winnie 26T: $166,340.00.
• 2025 Coachmen Cross Trail 26XG: $109,995
• 2025 Winnebago View 24D: from $184,00.00 to $189,000.00
• 2025 Entegra Odyssey 25R: from $124,995.00 to $175,960.00

While we can look at similar Class C rigs on the market, it’s necessary to look at each make and model in the floorplan that best suits your use, and compare specific features that are important to you while also considering your budget.

Grand Design’s first motorized RV, the Lineage Series M, appears to have been a nice foray into the space for those who can handle the (relatively) hefty price tag. Only time will tell whether these rigs will measure up in terms of longevity to popular stalwarts in the space such as Leisure Travel Vans and the like.

Built on the Ford F-600 4×4 Cab Chassis, the Lineage Series F boasts a 6.7L 4V 8-cylinder engine and a 10-speed automatic torque shift transmission.
