Safety technology includes Mobileye lane tracking, lane departure warning, OnGuard collision mitigation adaptive cruise, rain-sensing wipers, blind spot detection, and electronic stability control. 

  • 2027 Newmar London Air living room with TVs

    Room with a view

    Italian leather furniture, multiple seating configurations, and a 50-inch Samsung 4K TV create a true lounge-style living space, while the 43-inch overhead television adds another entertainment zone. Three 15K BTU heat pump air conditioners help keep the cabin comfortable, and Bluetooth integration through the Newmar app puts climate controls within easy reach. Between expansive windows, polished finishes, and standard Starlink connectivity, the 2027 Newmar London Aire makes it very easy to stay parked a little longer.

  • 2027 Newmar London Air cooking area

    Dining, upgraded

    A Samsung refrigerator with an icemaker, an all-electric induction flush-mount cooktop, a stainless steel convection microwave, and a large pantry make everyday meals feel far less like RV cooking. You can also add a dishwasher drawer, dual-zone beverage center, or narrow pantry beverage refrigerator for even more convenience. Heated tile flooring underfoot adds another premium detail that fits the overall tone of the coach.

  • 2027 Newmar London Air bed

    Suite dreams

    A king-size bed with a plush pillow-top mattress anchors the primary suite, joined by a Samsung television, dedicated wardrobe storage, and premium bedding finishes. Floor plan 4540 offers spacious midship bunks that can be converted into a dedicated desk-and-chair workspace, while floor plan 4545 allows you to convert the rear wardrobe into bunk beds.

    At Transwest, we only carry the best quality RV makes. Not only can we help you find exactly what you're looking for, but we also offer financing, parts, and service. Think of us as your one-stop-shop for RVs. Find the perfect RV for you.

    Frequently Asked Questions

    Can I finance an RV?

    Yes, RVs can be a big purchase, so there is a range of financing options available to keep you within budget. At Transwest, we have an in-house financing team that specializes in financing recreational vehicles. They know the industry as well as the needs of RVers, so they’re happy to help you find the right financing for your motorhome.

    What should I do with my old RV?

    We’ll buy it! At Transwest, we buy used RVs. In particular, we are always looking for late model Class A RVs, Class B RVs, Class C RVs, and Super C RVs, although we’re happy to discuss other types of RVs you’d like to sell. Submit an inquiry to get started.

    Who handles the title work when financing an RV?

    Our team at Transwest takes care of the title work when you finance an RV.

    What if I want to add upgrades or accessories to my RV?

    One of the great aspects of an RV is customizing it to your needs and wants. At Transwest, we have a full RV parts department that carries both mechanical parts and additional accessories for sale. You’ll be able to find the add-ons that help make your RV feel like home.

    Do I need a certain credit score to finance an RV?

    While credit history definitely factors into your financing options, don't get too hung up on having a certain score. Part of the reason we work with several different lenders is so that we have options that work with as many lifestyles and budgets as possible. Instead of wondering if you'll qualify, the best thing to do is start the process and our team will guide you through it.
