Newmar New Aire RV for Sale in Boise, ID
A full 450 hp diesel pusher in a 35-foot package. The New Aire goes where 43-foot coaches cannot, without giving up the Cummins power or the Newmar finish. Shop it at our Boise-area store serving the Treasure Valley.
Big Coach Power, Short Coach Footprint
The New Aire answers a complaint we hear constantly: buyers want a real diesel pusher, but they are tired of being turned away from state parks, national park campgrounds, and older resorts with length limits. At about 35 feet 10 inches, the New Aire fits where a 43-foot coach simply cannot, and it does it without dropping down to a gas chassis.
The running gear is the honest surprise. This is not a de-tuned coach. You get the same Cummins L9 making 450 horsepower and 1,250 lb-ft of torque as the bigger Newmars, through an Allison 3000MH transmission, on a Freightliner XCR chassis with an optional Spartan K2. Pair that with Comfort Drive adaptive steering and a shorter wheelbase and it drives more like a large motorhome than a bus, which is exactly the point.
Newmar New Aire Specifications
The essentials at a glance. Exact figures vary by model year and floorplan, so confirm the specifics on the unit you are looking at.
What Stands Out About the New Aire
Gets Into More Places
Under 36 feet clears the length limits at a lot of state parks, national park campgrounds, and older resorts. If you have been turned away in a longer coach, this is the fix.
No Power Compromise
The same 450 hp Cummins L9 and 1,250 lb-ft as the larger coaches. In a shorter, lighter rig that translates into genuinely strong grade performance while towing.
Full-Wall Power Slide
One long slide does the heavy lifting, so a 35-foot coach opens into a living space that feels far larger than the exterior suggests.
Driver Assist Built In
Mobileye lane-departure warning, OnGuard collision mitigation with adaptive cruise, dual 10-inch Xite displays, Apple CarPlay, and push-button start.
New Aire Floorplans
The New Aire keeps a tight, well-sorted range instead of a long list. Recent years offer three plans, all at about 35 feet 10 inches, with several including a guest-friendly mid-cabin or half bath.
New Aire 3543
A long-running favorite in the line, with a layout built around the full-wall slide and easy day-to-day living.
New Aire 3545
Brought back by popular demand for recent model years. Worth comparing side by side with the 3543 before you decide.
New Aire 3547
The plan to look at if a bath-and-a-half setup matters to you in a coach this size.
Earlier Model Years
Older New Aire years offered a fourth plan. Ask us what is available used, since these hold their value well.
New Aire Compared to the Rest of the Lineup
The New Aire is the odd one out in the best way. Here is how it lines up against the coaches buyers usually cross-shop.
| Model | Power | Roughly | Who It Suits |
|---|---|---|---|
| Bay Star | Gas, Ford 7.3L V8 | 31 to 38 ft | First Class A on a gas chassis |
| New Aire | Diesel, 450 hp Cummins L9 | About 36 ft | Diesel power with short-coach access |
| Dutch Star | Diesel, 450 hp Cummins L | 38 to 43 ft | The best-selling all-rounder, strong for full-timing |
| Mountain Aire | Diesel, higher output | Longer | A step up in size, finish, and features |
| Essex and King Aire | Diesel, top output | Longest | Top of the Newmar range |

Newmar New Aire FAQs
How long is the Newmar New Aire?
About 35 feet 10 inches across the current floorplans. That length is the whole reason the coach exists: it fits into state parks, national park campgrounds, and older resorts that turn away coaches over 36 or 40 feet.
Is the New Aire a real diesel pusher?
Yes, and that is what separates it from other short Class A coaches. It is a rear-engine diesel pusher on a Freightliner XCR chassis, with a Spartan K2 option, carrying the same Cummins L9 rated at 450 horsepower and 1,250 lb-ft of torque found in the larger Newmars.
How many floorplans does the New Aire offer?
Recent model years offer three: the 3543, 3545, and 3547, all at about 35 feet 10 inches. Some earlier years offered a fourth. Several plans include a guest-friendly mid-cabin or half bath, which is unusual in a coach this size.
What is the difference between the New Aire and the Dutch Star?
Both are diesel pushers with 450 hp Cummins power. The Dutch Star runs 38 to 43 feet with more floorplans, more slides, and more living space, and it usually rides on a tag axle. The New Aire trades that length and space for access and maneuverability. Buyers who camp in state and national parks tend to choose the New Aire; full-timers who want maximum room tend to choose the Dutch Star.
Is the New Aire good for full-time living?
Couples do full-time in one, and the full-wall power slide makes the interior live big for its size. That said, if you need maximum storage and living space for two people year-round, compare it honestly against a Dutch Star before deciding. The New Aire wins on where you can take it, not on square footage.
Can the New Aire tow a vehicle?
Yes. With a gross combination weight rating around 48,600 pounds and 1,250 lb-ft of torque, towing a vehicle is well within its capability. Bring us the specifics on what you plan to tow and we will confirm the numbers for the exact coach.
Do you have Newmar New Aire coaches for sale in Boise?
