Air Vent Design

One notable aspect of Montana RVs is their innovative air vent design. These vents incorporate foam material with linking blocks, ensuring structural integrity and preventing compression. 

What sets them apart is the inclusion of a dead end chunk, creating a tourbillon-like zone that promotes smooth airflow. By allowing controlled turbulence in this area, the rest of the space maintains optimal airflow.

The plastic end caps are strategically placed to facilitate efficient airflow and prevent damage.

Air Ducts and Blade Pure System

Montana RVs take great care in the installation of their air ducts. The ducts feature double-flanged slots that provide a secure fit, minimizing the risk of air leakage. 

This ensures that the conditioned air is effectively delivered to the living area rather than being wasted in the attic ducting. The Blade Pure system is another noteworthy feature, designed to enhance airflow and optimize cooling efficiency. 

By creating a cyclone effect within the air duct, it maximizes the extraction of cold conditioned air into the living cavity of the RV, where it is most desired.

Roof Construction and Support

Montana RVs place a strong emphasis on the construction and support of the roof. To ensure stability and structural integrity, L-shaped aluminum brackets are used on the edges of the roof trusses.

This design allows the roof trusses to be directly supported by the sidewalls, providing additional strength. The roof structure is insulated using residential baton insulation, and a roll of Radiant Barrier material is employed to maintain proper temperature regulation.

The inclusion of a masking tape prevents any sharp edges from damaging the roof membrane. Additionally, an overlapping flange bracket prevents potential roof leaks caused by the natural inclination of the roof decking to return to its flat position.

Attention to Detail and Sealant Application

Montana RVs are known for their meticulous attention to detail, especially in terms of sealing joints and preventing water penetration. The use of high-quality sealants and tape ensures a watertight exterior, reducing the risk of leaks.

The transition between the roof decking and sidewalls is carefully managed to create a smooth and durable connection that protects the integrity of the roof membrane.

Slide-out Construction and Refrigeration Options

Slide-outs are an essential feature in many Montana RVs, and their construction is given particular attention. 

The slide-out roofs are exceptionally thick, providing durability and allowing for walkability. Montana RVs have embraced the Norco exact slide system for its proven reliability, offering peace of mind to owners. 

In terms of refrigeration options, customers can choose between an 18 cubic foot residential refrigerator equipped with a built-in inverter or a larger 20 cubic foot 12-volt compressor-driven refrigerator. Both options cater to different camping preferences and power requirements.


Montana RVs have established themselves as leaders in the high-end fifth wheel market, thanks to their meticulous construction and commitment to customer comfort.

From their innovative air vents to their robust slide-out systems, Montana RVs deliver a superior camping experience. The attention to detail, use of high-quality materials, and focus on reliability ensure that Montana RV owners can enjoy their adventures with confidence and luxury. 

With a well-deserved reputation for excellence, Montana RVs continue to set the standard for quality and craftsmanship in the RV industry.
