The 2026 Grand Design Imagine AIM 15RBA is a compact, ultra-light single-axle travel trailer designed for easy towing, simple setup, and efficient couples or solo camping. At just under 20 feet in length (about 19’8”) and a dry weight around 3,500 lbs, it’s built for buyers who want the freedom of RV travel without needing a large tow vehicle. This model focuses on smart space usage, residential-style comfort, and Grand Design’s signature build quality in a lightweight footprint.
Inside, the 15RBA offers a surprisingly functional layout for its size. The floorplan is designed around a front Murphy bed living system, allowing the main living space to transform from a lounge area into a full sleeping suite at night. During the day, the sofa seating provides a comfortable place to relax, work, or entertain, while large windows help keep the interior bright and open.
The kitchen is centrally located and efficient, featuring a 2-burner cooktop, convection microwave, and a 12V refrigerator, along with practical counter space and storage. It’s designed for light cooking and campground meals while maximizing usable living space in a compact trailer.
At the rear, the full bathroom layout is one of the standout features for a trailer this size. It includes a walk-in shower, toilet, vanity, and storage, giving it a true residential feel rather than a cramped compact RV setup. This rear bath design also helps separate living and bathroom areas for added comfort.
Built with Grand Design’s focus on durability and off-grid readiness, the AIM 15RBA includes a heated and enclosed underbelly, laminated construction, and upgraded insulation package for extended-season camping. Exterior features typically include a power awning with LED lighting, pass-through storage, solar prep, and a rear accessory hitch, making it versatile for bikes, cargo, or light adventure gear.
