My career in automotive sales began with a less than ideal car-buying experience of my own and I’ve spent the last 25 years making sure no one else ever has that same feeling. My value is providing a mix of aesthetic and mechanical consultation regarding the choices available within the brands I represent. I blend technical mastery with an understanding of market availability and customer needs.

Whether you’re looking for your first RV, trading up to a luxury diesel pusher, or adding the perfect trailer or truck to your lineup, I’d love to put my quarter-century of award-winning sales experience to work for you the same way I do for every client: honest, transparent, and 100% focused on making this the easiest (and most fun) vehicle purchase you’ve ever made.

Impressive exterior

The 2026 Supreme Aire's exterior is just as sophisticated as its interior. This model is now available in either a 116 or 126 Cascadia chassis, so all rides feel remarkably smooth and secure. This RV’s exterior also boasts plenty of storage, an outdoor cooler, and a 43-inch TV. No space is wasted in the 2026 Newmar Supreme Aire, and that includes the model’s magnificent, welcoming exterior.
Cockpit comforts

When you hit the road in a 2026 Newmar Supreme Aire, drivers and passengers alike will feel safe throughout the trip. Safety starts in the cockpit, and this principle is upheld in the 2026 Supreme Aire’s design. A full LCD display with touch controls simplifies driving, and this model now includes a rearview camera to maximize safety. There’s also plenty of storage upfront, so you don’t have to leave any of your favorite items behind.
Kitchen fit for company

Inside the 2026 Newmar Supreme Aire’s kitchen, cooking is a dream. With a convenient pantry, a 19.6 cubic foot WhirlpoolⓇ fridge, and all the drawer space you could ever need, travelers have room for food, utensils, and all other kitchen essentials. This coach also has a three-in-one Whirlpool microwave, convection oven, and air fryer, so there’s no need to worry about having access to easy meals. The nearby sleeper-booth dinette affords travelers space to cozy up and enjoy warm meals on the road.
Bedroom bliss

You’ll find serene privacy behind the walls of the 2026 Supreme Aire’s bedroom. Travelers can fall into this coach’s cozy king-sized bed and watch their favorite shows on the bedroom’s 43-inch TV. The bedroom also includes a large dresser with a wealth of storage space, so you’ll have room for clothes, towels, and everything else in between. Rest, relax, and unwind in the 2026 Supreme Aire’s bedroom retreat.
A bathroom you can’t beat

It’s important to have a bathroom you feel comfortable in, and the 2026 Supreme Aire’s bathroom delivers respite in spades. The roomy shower is ideal for washing up after long hikes, and the single-sink vanity is large enough to house all of your toiletries. There’s also a half-bath mid-coach, so the primary bathroom can remain a private oasis.
Comfort-filled cabin

In the 2026 Newmar Supreme Aire, the cabin space makes travelers feel right at home. The 50-inch pop-up TV paired with a BoseⓇ soundbar makes for an impeccable entertainment experience, and the trifold sofa doubles as a convenient Hide-a-Bed. If you opt to include theater seats in your coach, you’ll have the perfect spot to sit back, relax, and watch TV.
