2021 Newmar New Aire 3543

Compact Luxury Diesel with Spartan Power, Residential Features & Advanced Safety

The 2021 Newmar New Aire 3543 is a standout in the luxury compact diesel segment—delivering true Newmar craftsmanship, residential comfort, and big-coach technology in a highly manageable 35’10” length.
