The Cirrus 720 will begin with a limited run this first quarter. It targets the short bed three-quarter ton and one-ton market.
Later this summer we will launch the Cirrus 620, a true half-ton camper. Our weight target for the 620 is below 1,700 pounds with a center of gravity in the mid to lower 20-inch range. The 620 will be based on the 720’s footprint with component and layout changes to hit our weight and center of gravity target.
Will there actually be a Cirrus 670?
No, the 670 was just a prototype. We assign a “70” to our prototype campers. The campers that will go into production are the Cirrus 720 and the upcoming Cirrus 620.
What is the dry weight of the Cirrus 720?
The 2019 Cirrus 720 is 1,875 pounds dry.
When we fill the fresh water tank, add a 65-pound battery, and fill the 20-pound propane tank, we’re at 2,120 pounds wet. Add in the electric jacks, air conditioner, side awning, and all of the options, and the wet-with-options weight is 2,340 pounds.
That wet weight will be beyond the payload boundaries of most half-tons. It’s possible to payload match the Cirrus 720 to a very stout half-ton, but it is better suited to a three-quarter ton or one-ton truck.
Where is the center of gravity on the Cirrus 720?
The Cirrus 720’s center of gravity is 32-inches. It will need to be paired with 6.5-foot beds. There may be some 6.0-foot beds that also work. That said, we always advise our customers to carefully measure their truck and their camper before loading for the first time.
Tell us about the framing material, lamination, and other construction details of the Cirrus 720.
As we embarked in the design phase of a lighter series of Cirrus campers, we knew we had to get our weight down considerably. That is when we came across Coosa; a high density polyurethane foam board that weighs significantly less than plywood. Coosa is a popular product in the marine industry for its low weight and high rigidity.
For the 720, we started with our wood-free aluminum frame, closed cell foam, and Azdel composite laminated walls. From there, we were able to utilize Coosa for backing structural components in the walls, floors, and roof. Coosa lightened the camper and will be employed across all of our models in the coming months.
Aside from the arc at the back, we kept the aluminum roof, which is the same as the Cirrus 820 and 920. We wanted a walk-on roof with full-framing so that it has the same structural benefits as the 820’s roof. We also fully-enclosed the underside of the camper and added an Alde convector to provide additional heat for the enclosed water tanks.
