Under the hood, every Thor Quantum is built on the Ford E-Series chassis, with an optional Chevrolet chassis available on ESpec models. The chassis is paired 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 floor plans 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.
On the exterior, every Quantum floor plan includes lighted rotocast storage compartments, and most floor plans also include a MEGA-Storage™ compartment for the 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, and the KW29, LF31, and HS31 floor plans 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.

Inside the Thor Quantum, residential vinyl flooring runs throughout for easy cleanup (a meaningful feature for pet owners and families).

Many floor plans also include a flip-up countertop extension for additional prep space.

The LC28, KW29, LF31, and HS31 floor plans also come standard with a 100-watt rooftop solar charging system and power controller, and the LC28 offers an optional second auxiliary house battery for buyers who plan to spend extended time off-grid.
