2026 Quantum LC21
Other floor plans with a similar body style, feature mix, and price range, prioritizing other manufacturers and brands.
The LC21 gives you a real choice at the chassis level. Either the Ford E-Series 7.3L V8 with 325hp or the Chevy 6.6L V8 pushing 401hp and 464 lb-ft of torque, which is a meaningful decision worth thinking through before you order. Inside, the cabover bunk keeps the sleeping layout efficient, while the rear full bed gets its own USB charging center and a dedicated 12-volt outlet for CPAP users, a thoughtful touch on a 24-foot rig. The shower gets a skylight and a retractable door upgrade, and the power patio awning with integrated LED lighting means you're not fumbling around at dusk. The 4.0 kW dual gas/LP generator paired with an automatic transfer switch means you have a real off-grid fallback, not just a checkbox feature.
