Heat recovery ventilation (HRV), also known as mechanical ventilation heat recovery (MVHR), is an energy recovery ventilation system using equipment known as a heat recovery ventilator, heat exchanger, air exchanger, or air-to-air heat exchanger which employs a cross flow or counter-flow heat exchanger.

New for 2022 is the first-ever Silverado ZR2, Chevy's new flagship off-road truck and the latest addition to a successful lineup of off-road, factory-installed lifted trucks. The enhanced 2022 Silverado also features an elevated exterior design and a new, expressive interior with enhanced technology.

The 2020 Chevrolet Silverado HD will start at $35,695, including $1,595 for destination. Interestingly enough, that's actually $300 lower than the outgoing Silverado HD, but because it's newer, it has more features and more technology than its predecessor.
