101" Wide Drop-Frame SuperChassis

Exclusive Grand Design Super Chassis Design

101" Wide Body Chassis

A full 5” wider than many coaches in its class, the widebody chassis allows for more livable floor space with deeper sliderooms, wider sofas in rear lounge models, and space saving sliding pocket doors into the bathrooms…all at a shorter towing length.

Wide Rail Design

Heavy duty I-beam main rails are placed further outward on the chassis. This wider rail placement provides a more stable jack stance, and allows for the slideroom gearpacks to be enclosed inside the frame rails (rather than outside).

Exclusive Drop Chassis Design Creates Large Pass Through Storage Area

Constructed to a Superior Standard

Thermal Roof Design (R-40)*

Thermal Roof Design

Thermal Roof Design (R-40)*

Fiberglass insulation and a layer of radiant foil insulation cover the roof. Grand Design goes further by extending both insulation layers the full length of the roof and around to the bottom of the front cap. To maximize the effectiveness of the insulation, a vented attic allows condensation to escape the roof structure.

Fully Laminated Walls (R-11)*

Fully Laminated Walls

Fully Laminated Walls (R-11)*

Sidewalls, rear wall, slideroom endwalls and slideroom roof are all welded aluminum framed and laminated with rigid foam insulation. Many others use wood framing and soft fiberglass insulation in the rear wall and sliderooms that can settle over time and leave uninsulated air gaps.

Triple Insulated Main Floor (R-45)*

Triple Insulated Main Floor

Triple Insulated Main Floor (R-45)*

The underbelly is lined with a radiant foil insulation barrier (Layer 1) and then covered with fiberglass insulation (Layer 2). The main floor enhances the R-Value with yet another layer of fiberglass insulation (Layer 3).

Here is what customers have to say...

★★★★★

Definitely will recommend Grand Design RV’s to friend and family. Quality at its finest and top notch appliances

Eleanor C, NJ

★★★★★

You need to take a second look at Grand Design RVs. Grand Design’s newer models have redesigned frames . These frames are referred to as the “Omega” frame which is a much heavier frame. They also started putting on MORryde independence suspension making a big towing difference from night and day. They also offer a one piece composite roof and have eliminated the rubber membrane. These are all great feature’s. So take a second look!

JOHN B, NV

★★★★★

We purchased this RV in preparation for retirement. We looked at numerous brands before deciding on Grand Design. This unit is well built and has everything we were looking for.

MARK C, IL

★★★★★

Bought our 2nd Grand Design Solitude at the 2026 Tampa RV show. Didn't look anywhere else! Love the product, love the company, and love the fellowship of owners. The 2026 Solitude 414LJMJ is one of the newest models offering a side patio on a non-toy hauler. Also has a bunkhouse for our daughter and grandkids when they come with us. Campers Inn/Lazy Days of Tampa was great to work with. Picked the new RV up on January 30th and it has been great. We use the patio almost every day!
