Chassis, Cockpit, and Towing
Every Quantum rides on the Ford E-Series chassis, with an optional Chevrolet chassis available on ESpec models. The chassis pairs with cruise control and an 8,000-pound trailer hitch, leaving room to tow a small toad, boat, or utility trailer behind the coach. ESpec floor plans include a 7-inch touchscreen dash radio with Apple CarPlay, Android Auto, Bluetooth, and SiriusXM Radio capability. The LC28, KW29, LF31, and HS31 step up further with the SmoothTech suspension system and a 10-inch touchscreen dash radio that doubles as a Touch N' Go Control panel for managing RV systems from a single interface.
Exterior, Awning, and Storage
Every Quantum floor plan includes lighted rotocast storage compartments, and most plans add a MEGA-Storage compartment for larger gear that families and full-time travelers tend to bring along. A power patio awning with integrated LED lighting is standard across the lineup. The KW29, LF31, and HS31 add a 32-inch exterior Smart TV with Bluetooth soundbar (optional on the LC28). The LC28 and HS31 also offer an optional pull-out exterior kitchen with griddle and 12-volt cooler for full-service outdoor cooking at the campsite.
Connectivity and Entertainment
Every ESpec floor plan includes a 32-inch Smart TV with a manual swivel mount in the cab-over bunk area. The LC28, KW29, LF31, and HS31 step up with a 40-inch Smart TV in the living area and the Winegard ConnecT 2.0 system, which combines a Wi-Fi router, 4G hotspot, and TV antenna in a single rooftop unit. The KW29, LF31, and HS31 also add a 32-inch Smart TV in the bedroom. The LZ22, LZ25, and LC28 come bedroom-TV-prepped for buyers who want to add their own.
Interior, Living, and Seating
Residential vinyl flooring runs throughout for easy cleanup, a meaningful feature for pet owners and families. Most floor plans include the Dream Dinette, which converts from dining space into an extra bed. The LC19 replaces the dinette with a rear U-dinette that also converts to a sleeping space. The LC28, KW29, LF31, and HS31 come standard with a jack-knife sofa, with optional theater seating with footrests available as an upgrade.
Galley
The kitchen varies by floor plan tier. Every Quantum includes a 12-volt refrigerator and a single-bowl stainless-steel sink with pull-down sprayer. Most floor plans add a two-burner gas cooktop. The KW29, LF31, and HS31 step up to a two-burner gas cooktop with a single induction burner. All ESpec models include a convection microwave oven with air fryer mode. The LC28 goes further with a recessed three-burner gas cooktop with oven plus a separate microwave. Many plans also include a flip-up countertop extension for extra prep space.
Sleeping
The Quantum lineup is built around floor plan flexibility. The LC21 uses a full-size bed. The LC28, LF31, HS31, and LZ22 use Queen-size beds. The KW29 steps up to a King-size bed. The LC19 uses a rear U-dinette that converts into a sleeping space. The LZ25 uses twin beds that combine into a King when needed. Every Quantum floor plan includes a cab-over bunk with a ladder and built-in cup holders. The LF31 adds dedicated bunk beds for families with kids. The Dream Dinette and jack-knife sofa also convert into extra sleeping spaces on select layouts.
Solar and Off-Grid
Every Quantum ESpec model is solar-prepped with a roof backer and pre-routed wiring to the kitchen base cabinet, so aftermarket solar installation is straightforward. The LC28, KW29, LF31, and HS31 come standard with a 100-watt rooftop solar charging system and power controller. The LC28 offers an optional second auxiliary house battery for buyers who plan to spend extended time off-grid.
