Features may include:

Automotive

• All Quantum® RVs are built on the Ford® E-Series chassis, with ESpec models offering an optional Chevrolet® chassis. Thanks to cruise control and the 8,000-pound trailer hitch, you'll enjoy a comfy ride. ESpec layouts include a 7-inch touchscreen dash radio with Apple CarPlay®, Android Auto™, Bluetooth®, and SiriusXM-Ready® capabilities. The LC28, KW29, LF31, and HS31 floor plans take it further with the SmoothTech™ suspension system and a 10-inch touchscreen dash radio with the same connectivity features that doubles as a Touch N’ Go Control™ panel, letting you manage RV functions from one convenient interface.

Exterior

• Stay organized and enjoy the outdoors with the Quantum®, which features lighted rotocast storage compartments on all models and a MEGA-Storage™ compartment on most floor plans. After a day of exploring, unwind under the powered patio awning with integrated LED lighting and take in the views. For even more outdoor enjoyment, the KW29, LF31, and HS31 layouts have a 32-inch Smart TV and Bluetooth® soundbar, while the LC28 offers it as an option. The LC28 and HS31 also have the option for a pull-out kitchen with a griddle and 12-volt cooler, perfect for cooking and entertaining outside.

Entertainment

• After setting up camp, enjoy your favorite shows on the 32-inch Smart TV with a manual swivel, conveniently located in the cab-over bunk area of every Quantum® ESpec floor plan. The LC28, KW29, LF31, and HS31 models take it up a notch with a 40-inch Smart TV in the living area and a versatile Winegard® ConnecT™ 2.0 system, which functions as a Wi-Fi router, 4G hotspot, and TV antenna. For more viewing options, watch movies on the 32-inch Smart TV in the bedroom of the KW29, LF31, and HS31 layouts, or take advantage of the bedroom TV prep in the LZ22, LZ25, LZ28, and LC28.

Living Area

• Built for life on the road, the Quantum® Class C RV combines comfort, durability, and innovative design with easy-to-clean residential vinyl flooring, perfect for pet owners. Most floor plans include the versatile Dream Dinette®, which effortlessly converts from a dining area to an extra bed, while the LC19 features a spacious rear U-dinette that transforms into a sleeping space. In the LC28, KW29, LF31, and HS31 layouts, you'll appreciate the stylish interior and the option to relax on the standard jack-knife sofa or upgrade to the optional theater seating with footrests for added comfort.

Kitchen

• Ditch the takeout and cook your favorite meals inside the Quantum®, which includes a 12-volt refrigerator and a single-bowl stainless-steel sink with a pull-down sprayer. Most models also feature a two-burner gas cooktop, while select layouts offer upgraded cooking options like a two-burner gas cooktop with a single induction burner in the KW29, LF31, and HS31, a convection microwave oven with an air fryer in all ESpec models, or a recessed three-burner gas cooktop/oven with a microwave oven in the LC28. Many floor plans also have a flip-up countertop extension for additional prep space.

Sleeping Area

• Rise and shine in the Quantum®. The LC21 floor plan features a cozy full-size bed, while the LC28, LF31, HS31, LZ22, and LZ28 include Queen-size beds, and the KW29 upgrades your sleep with a luxurious King-size bed. For added flexibility, the LC19’s rear U-dinette converts into a spacious bed, and the LZ25 features twin beds that can be combined into a King. All models include a cab-over bunk with a ladder and built-in cup holders, while the LF31 also offers bunk beds for families. Plus, the Dream Dinette® and jack-knife sofa on select layouts provide even more sleeping options, so everyone has a comfortable resting place.

Solar

• Every Quantum® is built for off-grid adventures, with solar readiness that lets you travel farther. All ESpec models include a solar prep roof backer and pre-routed wiring to the kitchen base cabinet, making it easy to install solar panels and power your appliances with clean energy. At the same time, the LC28, KW29, LF31, and HS31 floor plans have a 100-watt solar charging system with a power controller to maintain your RV’s house batteries. For even more energy on the go, the LC28 offers the option of a second auxiliary house battery, so you’re always ready to embrace the road less traveled.
